WebFeb 22, 2012 · L1(0) FePt is an important material for the fabrication of high density perpendicular recording media, but the ultrahigh coercivity of L1(0) FePt restricts its use. Tilting of the magnetic easy axis and the introduction of a soft magnetic underlayer can solve this problem. However, high temperature … 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.
WebMay 18, 2024 · When the easy axis is along the film normal, as is found for SRO 110, an in-plane magnetic field in the direction of the applied current is needed for the magnetization switching to be deterministic. In SRO 001 , where the easy axis is tilted, on the other hand, the symmetry is broken with respect to the in-plane SOT; this makes it possible to ... 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.
