Spin-orbit torque (SOT) is a type of current-induced torque with great potential for spintronic applications. SOTs result from spin-orbit coupling, usually when a charge current causes spin polarisation in a material with broken spatial inversion symmetry. However, the fundamental physics behind SOTs is not entirely understood.
After a brief introduction to the field of condensed-matter physics (which has a strong historical connection to the Cavendish Laboratory), Laurel discusses this interesting phenomenon along with skyrmions — another fascinating physical effect observed in magnetic materials.
