Physics/자성체 2012. 1. 25. Diamagnetic, Paramagnetic, and Ferromagnetic Materials When a material is placed within a magnetic field, the magnetic forces of the material's electrons will be affected. This effect is known as Faraday's Law of Magnetic Induction. However, materials can react quite differently to the presence of an external magnetic field. This reaction is dependent on a number of factors, such as the atomic and molecular structure of the material, and the net mag..

Physics/자성체 2011. 12. 9. The two-current model, The spin-valve type GMR effect The two-current model The physical origin of GMR is the electron spins effect on the electronic transport in ferromagnetic conductors. The first proposal by Mott described the spin splitting of the energy bands in the ferromagnetic spin states induces the specific transport behavior. Then, Fert and Grünberg experimentally demonstrated the spin dependent conduction in ferromagnetic metals and a s..
Physics/자성체 2011. 12. 9. Magnetic anisotropy Is there a relation between magneto-crystalline anisotropy and the orbital moment?A spin-reorientation from in-plane to out-of-plane occurs when the magneto-crystalline anisotropy favors an out-of-plane magnetization and is large enough to overcome the shape anisotropy. The magneto-crystalline anisotropy and hence the perpendicular magnetic anisotropy is given by the anisotropy in the spin-orbit..
