Book Description
This book introduces new concepts in the phenomenon of 1st order phase transitions. It discusses the concept of kinetic arrest at a certain temperature, with this temperature being dependent on the second control variable (magnetic field, or pressure). It discusses interesting manifestations of this phenomenon when the 1st order transition is broadened, i.e. occurs over a finite range of temperatures. Many examples of this phenomenon, observed recently in many materials, will also be discussed.

Magnetic Phase Transitions In Single Crystals
Author: Daivd P Belanger
Publisher: World Scientific
ISBN: 981125950X
Category : Science
Languages : en
Pages : 246
Book Description
Magnetic crystals are ideal systems to study the universal properties of phase transitions, particularly systems with quenched randomness and frustration. Pure systems with different symmetries provide the foundation for studies in corresponding systems with quenched randomness. Because phenomena near phase transitions have universal properties, results from bulk magnetic crystals provide a basis for understanding phase transitions in films and nanoparticles, as well as many non-magnetic materials.This motivates the subject of this book, which discusses phase transitions studies in magnetic crystals from the perspective of an experimentalist who has done extensive work in the field. The advantage is that many experimental techniques are described in sufficient detail for a good understanding of the results and their comparison to theory.

Field Induced First Order Phase Transition in Magnetic Systems
Author: Suryanarayan Dash
Publisher: LAP Lambert Academic Publishing
ISBN: 9783659662515
Category :
Languages : en
Pages : 148
Book Description
First order magnetic phase transition (FOMPT) in magnetic materials has been of numerous interests in recent past due to their unique functional properties like colossal magnetoresistance, giant magnetocaloric effect etc. Many of these functional magnetic materials are multicomponent systems whose properties become more interesting under substitutions. Such substitutions are the intrinsic source of frozen disorder which leads to the broadening of the first order transition. In this work role of chemical disorder has been studied in such functional oxides systems. Bulk measurement on these materials shows some anamolous feature at low temperature which were explained in terms of "kinetic arrest" which also responsible for the functionality of those materials. This work also gives an idea about the simultaneous effect of high pressure and magnetic field on such transition. Effect of magnetic field on the dielectric parameter of such functional oxides renders an important breakthrough. Moreover, similar studies been performed with shape memory alloys as an comparison.

Tabulation of First Order Magnetic Phase Transitions
Author: Charles S. Naiman
Publisher:
ISBN:
Category :
Languages : en
Pages : 26
Book Description
A literature search has been carried out and a tabulation has been made of all known first order magnetic phase transitions. The table includes all substances which have been found to undergo such phase transitions, and their relevant characteristics have been studied. The search has been conducted up to July 1963. One kind of transition (the so-called 'spin-flopping' type) exists for a very large class of materials. Since it can be characterized analytically in terms of other parameters of these materials, it was felt preferable to give a discussion of this transition, rather than an exhaustive literatue search. In order to properly guide the nature of the search, a definition of first order magnetic phase transitions is formulated in terms of familiar thermodynamic quantities. Sone of the implications of this definition are discussed. An example of a first order magnetic phase transition is discussed (AF - AF spin flop), and characterized by three parameters: anistropy energy, and parallel and perpendicular susceptibilities.

Reconstructive Phase Transitions
Author: Pierre Toldano
Publisher: World Scientific
ISBN: 9789810223649
Category : Science
Languages : en
Pages : 424
Book Description
This book deals with the phenomenological theory of first-order structural phase transitions, with a special emphasis on reconstructive transformations in which a group-subgroup relationship between the symmetries of the phases is absent. It starts with a unified presentation of the current approach to first-order phase transitions, using the more recent results of the Landau theory of phase transitions and of the theory of singularities. A general theory of reconstructive phase transitions is then formulated, in which the structures surrounding a transition are expressed in terms of density-waves, providing a natural definition of the transition order-parameters, and a description of the corresponding phase diagrams and relevant physical properties. The applicability of the theory is illustrated by a large number of concrete examples pertaining to the various classes of reconstructive transitions: allotropic transformations of the elements, displacive and order-disorder transformations in metals, alloys and related structures, crystal-quasicrystal transformations.

Elements of Phase Transitions and Critical Phenomena
Author: Hidetoshi Nishimori
Publisher: Oxford University Press
ISBN: 0199577226
Category : Science
Languages : en
Pages : 373
Book Description
As an introductory account of the theory of phase transitions and critical phenomena, this book reflects lectures given by the authors to graduate students at their departments and is thus classroom-tested to help beginners enter the field. Most parts are written as self-contained units and every new concept or calculation is explained in detail without assuming prior knowledge of the subject. The book significantly enhances and revises a Japanese version which is a bestseller in the Japanese market and is considered a standard textbook in the field. It contains new pedagogical presentations of field theory methods, including a chapter on conformal field theory, and various modern developments hard to find in a single textbook on phase transitions. Exercises are presented as the topics develop, with solutions found at the end of the book, making the text useful for self-teaching, as well as for classroom learning.
