In physics, a ferromagnetic material is said to have magnetocrystalline anisotropy if it takes more energy to magnetize it in certain directions than in others. These directions are usually related to the principal axes of its crystal lattice. It is a special case of magnetic anisotropy.
10 Dec 2014 shape anisotropy determines the orientation of the magnetization at any temperature. It is also shown that the. Callen-Callen law cannot be used to describe the temperature dependence of the perpendicular anisotropy in. Mn5Ge3. Such temperature dependence of the magnetocrystalline anisotropy shows
Abstract. Hard direction magnetization recoil curves were analysed taking into account the angular distribution of grain axes for textured Sm2Fe15?x Cux Si2C (x = 0 and 1) samples. Magnetocrystalline anisotropy constants K1 and K2 were determined in the temperature range between 1.5 K and 300 K using the textured

26 Jun 2001 a specific, high symmetry, crystallographic direction. Nevertheless, the energy cost per atom to align the magnetization along some other direction can be remarkably small. For example, the measured magnetocrystalline anisotropy (MCA) energy EMCA = E(0001) ? E(1010) is only ? 60 µeV per atom for
The problem of the magnetocrystalline anisotropy energy. MAE in the ferromagnetic 3d metals Fe, Co, and Ni is one of the longest standing and still incompletely solved prob- lems in the field of metallic magnetism.1–5 The MAE, which is the energy that directs the magnetization along a certain crystallographic axis, called

The dependence of the magnetocrystalline anisotropy energy (MAE) of MCo5 (M = Y, La) on the Coulomb correlations and strength of spin orbit (SO) interaction within the GGA + U scheme is investigated. A range of parameters suitable for the satisfactory description of key magnetic properties is determined. The origin of
