Fundamentals of Magnetism and Spintronics, develops the idea of magnetism, understand its sources and other related matters step by step. Fundamentals of Magnetism and Spintronics, describes microscopic sources of magnetic field and explains why different bodies behave differently in the presence of an external magnetic field. Different topics in Magnetism and Spintronics have been presented in simple ways using simple mathematics.
The objectives are to cover the basic concepts of Magnetism and Spintronics using simple models and to provide coverage of the subject matter as far as possible. Chapters 1 to 3 have been devoted to define the microscopic source of magnetism and to define fundamental parameters of magnetism. Chapter 4 to Chapter 11 have been devoted for the general properties of magnetic materials. There has been tremendous research in the field of material science and magnetism and as a result remarkable success has been achieved in magnetic storage technology.
A new subject known as spintronics or magneto-electronics has come up, which is a novel kind of union of elements of material science, magnetism and electrical engineering, with a goal to create devices and architectures for digital electronics applications. Chapter 12 has been devoted to introduce this subject to the students. Simple pictures and heuristic descriptions have been given to introduce basic ideas of spintronics, transport of spin polarized electrons, mechanisms by which several magnetoelectronic devices operate, and basic architectures of MRAM.
