For most magnetically anisotropic materials, there are two easiest directions to magnetize the material, which are a 180° rotation apart. The line parallel to these directions is called the easy axis. In other words, the easy axis is an energetically favorable direction of spontaneous magnetization. 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 magnetic anisotropy of a given object is often explained by a combination of these different factors: Magnetocrystalline … 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 Uniaxial 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. Each of these unsaturated functional groups (A-D) create a tiny magnetic field and hence some local anisotropic regions … See more • Fluorescence anisotropy See more • Tyablikov, S. V. (1995). Methods in the Quantum Theory of Magnetism (Translated to English) (1st ed.). Springer. ISBN See more WebMagnetocrystalline anisotropy (MCA) is the tendency of the magnetization to align itself along a preferred crystallographic direction. The easy and hard directions arise from the interaction of the spin magnetic moment with the crystal lattice (spin-orbit coupling) [29].In the presence of the external magnetic field, the spin of the electron tends to orient in the … the employee ownership trust

WebMagnetic easy axis. Fig. 9. Magnetic field dependence of the magnetization at selected temperatures for a 150-nm thick Ga xMn As film with a Mn composition x = 0.03S. The magnetic field is applied parallel to the sample surface (direction of magnetic easy axis) except for the closed circles at 5 K taken in perpendicular geometry. WebApr 13, 2024 · The easy and hard-axis loops are not easily distinguishable as the coercivity, remanence, saturation fields and loop energy are of very little difference. The reason could be due to the formation of vortex states in the nanospheres. To understand the reason behind this leads us to study the magnetisation reversal behavior of the chains … WebFigure 28 shows the easy and hard axis magnetization curves for the two principal Co-Sm magnets and Fe 14 Nd 2 B (see also Table V).
