Collective skyrmion motion under the influence of an additional interfacial spin-transfer torque [PDF]
Scientific Reports, 2022 Here we study the effect of an additional interfacial spin-transfer torque, as well as the well-established spin–orbit torque and bulk spin-transfer torque, on skyrmion collections—group of skyrmions dense enough that they are not isolated from one ...
