Magnetic skyrmions have a robust topological magnetic structure, which makes them ideal for use as binary information carriers. The skyrmions appear in a well-ordered lattice state in cubic B20 helimagnets, which can be collectively manipulated by electric currents, thermal, and magnetic gradients. Recently, we have shown that skyrmion lattices in Cu2OSeO3 rotate in radial magnetic field gradients. Here, we propose a systematic study of the response of the skyrmion lattice in MnSi to radial thermal gradients, again expecting a circular motion of the lattice.
