DOI: 10.1063/5.0140328
Abstract: We report current-induced magnetization switching in Pt/Co/Ir/Co/Pt multilayers with different Ir layer thicknesses ( tIr), where the perpendicularly magnetized Co layers are coupled ferromagnetically or antiferromagnetically through an interlayer exchange coupling and are sandwiched by… read more here.

DOI: 10.1103/physrevx.9.021017
Abstract: We present an extensive overview of the phase diagram, spin-wave excitations, and finite-temperature transitions of the anisotropic-exchange magnets on an ideal nearest-neighbor triangular lattice. We investigate transitions between five principal classical phases of the corresponding… read more here.

DOI: 10.1177/09544100211064759
Abstract: The dual-spin-stabilized projectile’s mechanism of angular motion is analyzed, taking into account the two pairs of fixed-canards. Based on the non-homogeneous terms of the angle of attack (AOA) equation, the gyroscopic stability and precession feature… read more here.
