Magnetic skyrmion diode: Unidirectional skyrmion motion via symmetry breaking of potential energy barriers

“…In this nanostrip, a Néel-type magnetic skyrmion is initially located at R 0 = (x 0 , y 0 ) = (±274, 0) nm on either the left or right side relative to the pinning-site center. We can generate a skyrmion at R 0 as proposed in various ways [51][52][53][54]. The skyrmion is driven to move toward the pinning site by applying in-plane dc currents in opposite (±x) directions.…”
