Magnetoelastic effects in the YFe₁₀V₂ ferromagnetic alloy

Abstract

PACS 65.40. De, 75.50.Bb, 75.80.+q Magnetoelastic effects in the YFe 10 V 2 alloy between 5 and 300 K, and under magnetic fields up to 6 T are studied. Results show that spontaneous magnetostriction of the sample is positive in agreement with what is observed in similar iron based compounds and with the well known increase of the exchange interactions with interatomic distances. Two mechanisms of the forced magnetostriction, in polycrystalline samples, were clearly identified. The mechanism associated with the rotation of magnetization is of single ion origin and leads to a negative contribution to the volume magnetostriction. The other mechanism, mainly of two ions origin, is the same as the one responsible for the spontaneous magnetostriction.

Influence of H and N insertion on the magnetostriction and thermal expansion of YFe10V2Zx (Z=N, H) compositions

“…2a). These variations are similar to those previously reported for polycrystalline samples of the YFe 10 V 2 alloy [14,15]. However, the data of the present study are about 30% larger than in the previous study.…”
