Breathing Mode of a Skyrmion on a Lattice
Dmitry A. Garanin, Reem Jaafar, Eugene M. Chudnovsky
The breathing mode of a skyrmion, corresponding to coupled oscillations of its size and chirality angle is studied numerically for a conservative classical-spin system on a $500\ti…
Graphene Cantilever Under Casimir Force
Amel Derras-Chouk, Eugene Chudnovsky, Dmitry Garanin +1
Stability of graphene cantilever under Casimir attraction to an underlying conductor is investigated. The dependence of the instability threshold on temperature and flexural rigidi…
Manipulating Magnetization of a Nanomagnet by Surface Acoustic Waves: Spin-Rotation Mechanism
Eugene M. Chudnovsky, Reem Jaafar
We show that the magnetic moment of a nanoparticle embedded in the surface of a solid can be switched by surface acoustic waves (SAW) in the GHz frequency range via a universal mec…
Electromechanical Magnetization Switching
Eugene M. Chudnovsky, Reem Jaafar
We show that the magnetic moment of a composite multiferroic torsional oscillator can be switched by the electric field. The 180 switching arises from the spin-rotation couplin…
Mechanically-Assisted Current-Induced Switching of the Magnetic Moment in a Torsional Oscillator
Liufei Cai, Reem Jaafar, Eugene M. Chudnovsky
Switching of the direction of the magnetic moment in a nanomagnet is studied within a modified Slonczewski's model that permits torsional oscillations of the magnet. We show that t…
Deflagration with quantum and dipolar effects in a model of a molecular magnet
D. A. Garanin, Reem Jaafar
Combination of the thermal effet in magnetic deflagration with resonance spin tunneling controlled by the dipole-dipole interaction in molecular magnets leads to the increase of th…
