Title:
Rotating Skyrmion Lattices by Spin Torques and Field or Temperature Gradients
Abstract:
Chiral magnets like MnSi form lattices of skyrmions, i.e., magnetic whirls, which react sensitively to small electric currents j above a critical current density jc. The interplay of these currents with tiny gradients of either the magnetic field or the temperature can induce a rotation of the magnetic pattern for j\$>\$jc. Either a rotation by a finite angle of up to 15\$i̧rc\$ or\textemdash{}for larger gradients\textemdash{}a continuous rotation with a finite angular velocity is induced. We use La...    »
