This book presents a study of magnetization switching dynamics in ferromagnetic nanofilms and nanopillars. The dynamics of the switching process is understood by solving the Equation of motion with Gilbert damping and Equation of motion with Gilbert damping and spin transfer torque respectively both analytically and numerically. The major issues considered in the book is to identify the possible ways to reduce the switching time and to minimise the critical/threshold field or current required to induce switching in the ferromagnetic nanofilms or nanopillars. Specifically, the impact of...
