Search for magnetoelectric monopole response in CrO powder

Syed Q. A. Shah, Ather Mahmood, Arun Parthasarathy +1

Powder samples have been suggested as a pathway to fabricate isotropic magnetoelectric (ME) materials which effectively only have a pseudoscalar or monopole ME response. We demonst…

Switching time of spin-torque-driven magnetization in biaxial ferromagnets

Ankit Shukla, Arun Parthasarathy, Shaloo Rakheja

We analytically model the magnetization switching time of a biaxial ferromagnet driven by an antidamping-like spin torque. The macrospin magnetization dynamics is mapped to an ener…

Precessional spin-torque dynamics in biaxial antiferromagnets

Arun Parthasarathy, Egecan Cogulu, Andrew D. Kent +1

The Néel order of an antiferromagnet subject to a spin torque can undergo precession in a circular orbit about any chosen axis. To orient and stabilize the motion against the effec…

Phenomenological description of the dynamics of bipartite antiferromagnets in the limit of strong exchange

Arun Parthasarathy, Shaloo Rakheja

The equation of motion of the staggered order parameter is derived in a step-by-step manner from the coupled Landau-Lifshitz-Gilbert dynamics of bipartite spin moments in the limit…

Dynamics of Magnetoelectric Reversal of Antiferromagnetic Domain

Arun Parthasarathy, Shaloo Rakheja

When electric and magnetic fields are applied together on a magnetoelectric antiferromagnet, the domain state is subject to reversal. Although the initial and final conditions are…

Reversal Time of Jump-Noise Dynamics for Large Nucleation

Arun Parthasarathy, Shaloo Rakheja

The jump-noise is a phenomenological stochastic process used to model the thermal fluctuation of magnetization in nanomagnets. In this work, the large nucleation regime of jump-noi…
