WebThe anisotropy field separating the easy and hard axes is 13 T, unexpected for the Mn ions with nominally negligible orbital momentum and spin-orbit interactions. WebIt is an experimental fact that ferromagnetic single crystals exhibit ‘easy’ and ‘hard’ directions of the magnetization; i.e. the energy required to magnetize a crystal depends on the ...
WebJan 27, 2024 · Figure 4 presents the temperature dependent magnetization, which also shows a similar trend, where the magnetization was the highest in the easy and the lowest in the hard axes of the aligned film compared to the Random film with intermediate magnetization. All films retain the same broad transition with dM/dT peaking at ∼320K. 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.

WebIn a two-dimensional easy-plane Heisenberg model with a magnetic field along the hard axis, switching between different vortex states (parallel and antiparallel to the field) was studied by means of a Monte Carlo simulation. The vortex-core magnetization appears to be conserved, whether a magnetic field is present or not.
Webthe magnetization. The hard axis loop, where the hard axis is at right angles to the easy axis, is more or less linear and generally hysteresis free, i.e., the magnetization is reversible.
