Stochasticity in the Switching of Nanodisks for Probabilistic Computing Open
Stochasticity in magnetic nanodevices is an essential characteristic for harnessing these devices to computing based on population coding or the building blocks of probabilistic computing, p-bits. A magnetic tunneling junction (MTJ) consis…

Magnetic skyrmion diode: Unidirectional skyrmion motion via symmetry breaking of potential energy barriers Open
We realize a magnetic skyrmion diode operated by a unidirectional skyrmion transport that flows in only one direction, which is highly significant for information processing in spintronic and nanoelectronic devices. We easily control the s…

Topology-dependent stability of vortex-antivortex structures Open
The non-trivial topology of magnetic structures such as vortices and skyrmions is considered as a key concept to explain the stability of those structures. The stability, dictated by non-trivial topology, provides great potential for devic…

Geometric effects in cylindrical core/shell hard–soft exchange-coupled magnetic nanostructures Open
We explore the optimal condition for cylindrical core/shell hard-soft exchange-coupled magnetic nanostructures by obtaining full hysteresis loops for various geometries by obtaining full hysteresis loops for various geometrical variables, …
