Fundamentals of Magnetism and Spintronics

Description

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.

Dr . Atowar Rahman joined Gawahati University as a Junior Research Fellow in 1970 after completing his M.Sc. (Physics) from Gawahati University. He served B. Barooah College, Guwahati as a lecturer from 1972 to 1983. During this period he achieved Ph.D. from Gawahati University, and went to University of Nottingham (U.K.) as a post-doctoral research scholar in 1978. Dr. Rahman joined Gawahati University in 1983 as a lecturer. Subsequently
he became Reader and then Professor and served as the Head of the Department of Physics before retirement in 2007. He was reappointed as a Professor after retirement for five years till 2012. He had been teaching solid state physics specially magnetism, semiconductors and superconductivity in PG classes. He guided research students for their Ph.D. in various topics of solid state physics and published more than fifty research papers in international journals.
