NISHIHARA et al, 2004. NMR of 51V in a Heusler alloy Fe2VSi. Journal of Alloys and Compunds, 383(1-2), pp. 302-209
NMR experiments of 51V are reported for two samples of Fe2VSi: one is quenched after annealing at 1073K and the other is quenched
after annealing at 1123 K. Free-decay signals were observed at high temperature and the hyperfine coupling constant is determined to be
−5.0 ± 0.5 kOe/μB for both samples, indicating that the vanadium atoms do not carry a moment. The temperature dependence of the width
of the field-swept spin-echo spectra at low temperature is consistent with the commensurate and incommensurate anti-ferromagnetic spin
structures proposed from neutron experiments. The magnetism in Fe2VSi strongly depends on the degree of atomic order.
