Superconductivity assisted change of the perpendicular magnetic anisotropy in V/MgO/Fe junctions.

Managing the vertical magnetic anisotropy in thin movies has received considerable focus recently because of its technical relevance. Here we reveal that in V/MgO/Fe epitaxial joints with completing out-of-plane and in-plane magnetic anisotropies, the SOC mediated interaction in between a ferromagnet and a superconductor enhances the effective PMA below the superconducting shift. This creates a partial magnetisation reorientation with no applied field for almost the biggest joints, where the IP anisotropy is much more durable; for the tiniest joints there is a reduction of the field needed to cause a complete OOP shift as a result of the stronger competitors between the IP and OOP anisotropies. We additionally talk about just how the [Formula: see message] area might be influenced by the interaction in between magnetic stray fields and superconducting vortices.

Effects of Interfacial Termination, Oxidation, and Film Thickness on the Magnetic Anisotropy in Mn2.25Co0.75Ga0.5Sn0.5/MgO Heterostructures.

Vertical magnetic anisotropy is a determining factor for the understanding of nonvolatile info storage space devices with high effectiveness and thermal stability. In this work, a new spin gapless semiconductor Mn 2. 25 Carbon monoxide 0. 75 Ga 0. 5 Sn 0. 5 Heusler alloy with an inter-spin zero gap was first created in theory. With MCGS density raising from 5 to 16 monolayers, the PMA of MCGS/MgO heterostructures with an AC-type surface area reduces substantially. Nonetheless, the PMA of BD-type surface models is reasonably robust to the density of the MCGS layer, and the magnetic anisotropy constantly points to the out-of-plane instructions. For That Reason, MCGS Heusler alloy is a new encouraging spin gapless semiconductor prospect for spintronics applications. The tunable and robust PMA in MCGS/MgO heterostructures provides the possibility for developing nonvolatile information memory tools.
