Scaling of Coercivity in a 3d Random Anisotropy Model
Thomas C. Proctor, Eugene M. Chudnovsky, Dmitry A. Garanin
The random-anisotropy Heisenberg model is numerically studied on lattices containing over ten million spins. The study is focused on hysteresis and metastability due to topological…
Josephson junction with a magnetic vortex
R. Zarzuela, E. M. Chudnovsky, J. Tejada
We have studied Josephson tunneling through a circularly polarized micron or submicron-size disk of a soft ferromagnetic material. Such a disk contains a vortex that exhibits rich…
Ordered vs Disordered States of the Random-Field Model in Three Dimensions
D. A. Garanin, E. M. Chudnovsky
We report numerical investigation of the glassy behavior of random-field exchange models in three dimensions. Correlation of energy with the magnetization for different numbers of…
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…
