Mixed magnetism, nanoscale electronic segregation and ubiquitous first order transitions in giant magnetocaloric MnFeSiP alloys detected by ${}^{55}$Mn NMR

R. Hussain, F. Cugini, S. Baldini +8

We report on a study on a representative set of Fe${}_2$P-based MnFePSi samples by means of ${}^{55}$Mn NMR in both zero and applied magnetic field. The first-order nature of the mag…
