Abstract:
We report detailed low-temperature magnetotransport and magnetization measurements in MnSi under pressures up to $\sim$12kbar. Tracking the role of sample quality, pressure transmitter, and field and temperature history allows us to link the emergence of a giant topological Hall resistivity $\sim$50n$\Omega$cm to the skyrmion lattice phase at ambient pressure. We show that the remarkably large size of the topological Hall resistivity in the zero-temperature limit must be generic. We discuss vari...     »
