Complex magnetism in Fe2VSi
journal contribution
posted on 2006-05-11, 12:06 authored by H. Nishihara, K. Ono, Klaus-Ulrich Neumann, K.R.A. Ziebeck, T. KanomataMagnetic susceptibility and 51V NMR measurements are reported for two samples of the Heusler alloy Fe2VSi: Both
samples have been quenched, one after annealing at 1073 K (sample 1) and the other at 1123 K (sample 2). The
susceptibilities of both samples have been found to depend strongly on the applied static magnetic field. A new magnetic
transition is found at 300 K for sample 2. NMR line widths of 51V become appreciably broader at 80 K for sample 1
and at 150 K for sample 2. These temperatures do not correspond to the magnetic and crystallographic transition
temperatures determined by diffraction experiments. The NMR widths are governed by the combined effects of the
hyperfine fields from ferromagnetic iron clusters in the crystals and the intrinsic antiferromagnetic spin structures.
