Study of the influence of hydrogen absorption on the magnetic properties of V−Fe−H alloys by low-temperature Mössbauer spectroscopy

The change of the magnetic properties of disordered bcc V?Fe alloys induced by hydrogen absorption has been studied by the Mössbauer spectra measurements at 4.2 K. The magnetic ordering reflecting the para-/ferromagnetic transition was observed in these alloys as a result of hydrogenation, at the same electron concentration at which the local magnetic moments were observed by room-temperature measurements.
