Multiferroics can possess multiple ferroic orders, for example, electric polarization and magnetism, and are of interest for new device applications. Here thermal control is shown to manipulate electric and magnetic orders in a single-phase quasi-two-dimensional halide perovskite.
Employing a remote Coulomb superlattice formed by twisted bilayer WS2, the authors demonstrate the engineering and on/off switching of a Coulomb superlattice of correlated states in bilayer graphene with period and strength determined by the remote superlattice.
Plastic deformation requires the propagation of a kinked profile along dislocations. It is shown that each kink acts as a set of travelling thermal spikes, favouring the nucleation of supplementary kinks and long dislocation jumps that are observed experimentally.
