A magnetic particle with uniaxial anisotropy has one easy axis. If the easy axis is in the z {\displaystyle z} direction, the anisotropy energy can be expressed as one of the forms: E = K V ( 1 − γ 2 ) = K V sin 2 ⁡ θ , {\displaystyle E=KV\left(1-\gamma ^{2}\right)=KV\sin ^{2}\theta ,} See more In condensed matter physics, magnetic anisotropy describes how an object's magnetic properties can be different depending on direction. In the simplest case, there is no preferential direction for an object's See more The observed magnetic anisotropy in an object can happen for several different reasons. Rather than having a single cause, the overall … See more Suppose that a ferromagnet is single-domain in the strictest sense: the magnetization is uniform and rotates in unison. If the magnetic moment is $${\displaystyle {\boldsymbol {\mu }}}$$ and the volume of the particle is $${\displaystyle V}$$, … See more The magnetic anisotropy of a benzene ring (A), alkene (B), carbonyl (C), alkyne (D), and a more complex molecule (E) are shown in the figure.

WebMagnetic anisotropy [63] is the directional dependence of the material's magnetic moment. Because of anisotropy, there are preferred orientations of the magnetic … WebIn particular, the parallel alignment of spin order and the electric polarization vector render the magnetic anisotropy tunable via ferroelectricity, leading to intrinsic magnetoelectric coupling. Based on the results of the phonon spectrum and Born–Oppenheimer molecular dynamic simulation, the stability of the FeCl monolayer is confirmed. hydrocarbons naming rule

Application of DFT for magnetic anisotropy energy

WebSep 7, 2024 · To find the magnetic ground state between ferromagnetic (FM) and antiferromagnetic states, we also performed the total energy calculation. Both systems displayed FM ground state, and the energy differences were 68 meV and 49 meV per unit cell in the pristine and Janus systems. WebJul 2, 2024 · The dynamical simulation of the atomistic spin model and the corresponding micromagnetic simulation show that the planar surface magnetic anisotropy causes a reduction in the switching field of fine particles by approximately 20–30%, which may be relevant to the atomic-scale surface effects found in the experimental studies.
