Transverse field muon-spin rotation measurement of the topological anomaly in a thin film of MnSi
We have published a paper in Physical Review B 93, 140412(R) (2016). The abstract is below.
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.
