Qualitative resemblance between thin film and bulk MnSi data
Quantitative differences in magnetoresistivity
Differences attributed to spin fluctuation spectra
Abstract
We present a study of the magnetoresistivity of thin film MnSi in high magnetic fields. We establish that the magnetoresistivity can be understood in terms of spin fluctuation theory, allowing us to compare our data to studies of bulk material. Despite of a close qualitative resemblance of bulk and thin film data, there are clear quantitative differences. We propose that these reflect a difference of the spin fluctuation spectra in thin film and bulk material MnSi.
