Abstract: | Tc measurements for V1?xTixHy show that a decrease in Tc always occurs upon hydrogenation, but with slopes ( that change with x. A phenomenological model is suggested, associating the Tc decrease in most of the range of x to changes in nominal number of conducting electrons and in the volume induced by the hydrogenation. The model roughly accounts for the variations in Tc in the V-rich alloys. It fails to explain the Tc variation at the Ti end. |
