WebThe magnetization data is analyzed on the basis of crystalline electric field (CEF) model. 1 Introduction Ce based compounds are known to exhibit a variety of interesting behavior at low temperatures, such as normal trivalent, heavy fermion, mixed valent, Kondo lattice, and quantum phase transition tuned by pressure, doping or magnetic field. WebThe crystalline anisotropy is due fundamentally to the spin-orbit interaction which produces a direction within the crystal with minimum magnetic energy (easy axis).
WebJul 8, 2024 · The reason for these has been explained (with a diagram) as: Crystalline solids are anisotropic in nature, that is, some of their physical properties like electrical resistance or refractive index show different values when measured along different directions in the same crystals. WebJul 3, 2024 · For this purpose, we prepared Co x Fe 3−x O 4 NPs, with x = 0–1 in steps of 0.2, from soft magnetic (Fe 3 O 4) to hard magnetic (CoFe 2 O 4) ferrite, with a significant variation of the magnetic anisotropy. The phase purity and the formation of crystalline NPs with a spinel structure were confirmed through Rietveld refinement.
WebAmong the nanocrystals, the cobalt ferrite possessing magneto crystalline anisotropy is an apt material to investigate the super paramagnetic characteristics and inter particle … WebCrystal anisotropy means that easy axis and plane magnetization requires relatively less amount of work; therefore, it is also called magnetocrystalline anisotropy. In non-cubic …
WebCrystalline solids are anisotropic . Due to their differing refractive indices, anisotropic crystals exhibit birefringence, optical activity, dichroism, and dispersion. Crystalline …
The magnetocrystalline anisotropy parameters are generally defined for ferromagnets that are constrained to remain undeformed as the direction of magnetization changes. However, coupling between the magnetization and the lattice does result in deformation, an effect called … See more 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 See more The spin-orbit interaction is the primary source of magnetocrystalline anisotropy. It is basically the orbital motion of the electrons which couples with crystal electric field giving … See more The magnetocrystalline anisotropy energy is generally represented as an expansion in powers of the direction cosines of the magnetization.

Introduction … See more Magnetocrystalline anisotropy has a great influence on industrial uses of ferromagnetic materials. Materials with high magnetic anisotropy usually have high coercivity, that is, they are hard to demagnetize. These are called "hard" ferromagnetic … See more The magnetocrystalline anisotropy parameters have a strong dependence on temperature. They generally decrease rapidly as the temperature approaches the Curie temperature, so the crystal becomes effectively isotropic.
