Theory of Itinerant Electron Magnetism (International Series of Monographs on Physics, 106)

This book is an application of quantum mechanics and statistical mechanics to the field of magnetism. A large part of the book is devoted to a detailed treatment of the connections between electronic properties and magnetism, and how they differ in the various known magnetic systems. Current trends are exposed and explained for a large class of alloys and compounds. The modern field of artificially layered systems - known as multilayers - and their industrial applications are dealt with in detail. The book also relates the rich thermodynamic properties of magnets to the ab initio results originating from the electronic structure.

this Book, In The Broadest Sense, Is An Application Of Quantum Mechanics And Statistical Mechanics To The Field Of Magnetism. Under Certain Well Described Circumstances, An Immensely Large Number Of Electrons Moving In The Solid State Of Matter Will Collectively Produce Permanent Magnetism. Permanent Magnets Are Of Fundamental Interest And Magnetic Materials Are Also Of Great Practical Importance As They Provide A Large Field Of Technological Applications. The Physical Details Describing The Many Electron Problem Of Magnetism Are Presented In This Book On The Basis Of The Local Density Functional Approximation. The Emphasis Is On Realistic Magnets, For Which The Equations Describing The Many Electron Problem Can Only Be Solved By Using Computers. The Great, Recent And Continuing Improvements Of Computers Are, To A Large Extent, Responsible For The Progress In The Field. Along With A Detailed Introduction To The Density Functional Theory, This Book Presents Representative Computational Method And Proves The Reader With A Complete Computer Program For The Determination Of The Electronic Structure Of A Magnet On A Pc.

a Large Part Of The Book Is Devoted To A Detailed Treatment Of The Connections Between Electronic Properties And Magnetism, And How The Differ In The Various Known Magnetic Systems. Current Trends Are Exposed And Explained For A Large Class Of Alloys And Compounds. The Modern Field Of Artificially Layered Systems- Knows As Multilayers- And Their Industrial Applications Are Dealt With In Detail. Finally, An Attempt Is Made To Relate The Rich Thermodynamic Properties Of Magnets To The Ab Inition Results Originating From The Electronic Structure.

based Partly On His Lectures For Students With A Command Of Quantum Mechanics And Statistical Mechanics, And A Basic Knowledge Of Solid State Physics, Kbler (solid State Physics, Darmstadt U. Of Technology) Explores The Connection Between Electronic Properties And Magnetism, And How They Differ In The Various Known Magnetic Systems. He Looks At Trends In A Large Class Of Alloys And Compounds, Artificially Layered Systems, And Links Between The Rich Thermodynamic Properties Of Magnets And The Results Originating From The Electronic Structure. He Says His Treatise Is Too Long For A Course, But Suggests That Parts Of It Could Be Used For A Graduate Course On The Theory Of Magnetism. Annotation C.

This book, in the broadest sense, is an application of quantum mechanics and statistical mechanics to the field of magnetism. Under certain well described circumstances, an immensely large number of electrons moving in the solid state of matter will collectively produce permanent magnetism. Permanent magnets are of fundamental interest, and magnetic materials are also of great practical importance as they provide a large field of technological applications. The physical details describing the many electron problem of magnetism are presented in this book on the basis of the local density functional approximation. The emphasis is on realistic magnets, for which the equations describing the many electron problem can only be solved by using computers. The great, recent and continuing improvements of computers are, to a large extent, responsible for the progress in the field. Along with a detailed introduction to the density functional theory, this book presents representative computational methods and provides the reader with a complete computer programme for the determination of the electronic structure of a magnet on a PC. A large part of the book is devoted to a detailed treatment of the connections between electronic properties and magnetism, and how they differ in the various known magnetic systems. Current trends are exposed and explained for a large class of alloys and compounds.
