Magnetic Anisotropy Of Fine Particles Magnetic Anisotropy Of Fine Particles In nature, undivided domain particles are magnetized to saturation, where the magnetization has an easy axis, or several easy axes, along which it prefers to lie. In this case the complete internal postal code is minimum. Rotation of the magnetization vector away from the easy axis is possible only by applying an outside(a) magnetic field. This phenomenon is prefigureed magnetic anisotropy. Thus, the term magnetic anisotropy describe the dependence of the internal energy on the direction of magnetization of the particle. The energy term of this kind is called a magnetic anisotropy energy.
Generally it has the similar symmetry as the crystal structure of the particle material, and we call it a magnetocrystalline anisotropy or crystal anisotropy . This kind of anisotropy is due generally to spin-orbit coupling . For instance, we consider an anisotropy that is uniaxial in symmetry. In this case, one of the simplest expressions of ...If you want to get a full essay, order it on our website:
