DOI: 10.1088/1361-6463/ac4dcb
Abstract: In this article, we theoretically investigate the influence of strain on the oscillation frequency characteristics of a skyrmion-based spin-torque nano-oscillator (STNO) using micromagnetic simulations. The system consists of an ultrathin nanopillar magnetic film with interfacial… read more here.

DOI: 10.1103/physreva.101.053428
Abstract: We show that the stray field generated by isolated magnetic skyrmions can be used to trap ultracold atoms. Specially, ring-shaped and double-well trapping potentials for ultracold atoms can be created by combining the field from… read more here.
