Q2. describe the influence of magnetic anisotropy on the behavior of magnetic nano-particles.

Q3. describe the basic principle of a spin-valve device: discuss the relation between the magneto resistance and the magnetization of the materials changes with magnetic field.

Q4. describe the physical principles of tunneling magneto resistance and discuss the relevance of materials (electrodes and barrier) involved.
