On the temperature dependence of spin pumping in ferromagnet–topological insulator–ferromagnet spin valves
Results in Physics Elsevier 6 (2016) 293-294
Abstract:
Topological insulators (TIs) have a large potential for spintronics devices owing to their spinpolarized, counter-propagating surface states. Recently, we have investigated spin pumping in a ferromagnet-TI-ferromagnet structure at room temperature. Here, we present the temperature-dependent measurement of spin pumping down to 10 K, which shows no variation with temperature.Transverse field muon-spin rotation measurement of the topological anomaly in a thin film of MnSi

Abstract:
We present the results of transverse-field muon-spin rotation measurements on an epitaxially grown 40-nm-thick film of MnSi on Si(111) in the region of the field-temperature phase diagram where a skyrmion phase has been observed in the bulk. We identify changes in the quasistatic magnetic field distribution sampled by the muon, along with evidence for magnetic transitions around T≈40 and 30 K. Our results suggest that the cone phase is not the only magnetic texture realized in film samples for out-of-plane fields.
