Pronounced Change in the Low-Temperature Heat Capacity ofV3Si with Stress

摘要: A pronounced decrease of the heat capacity ${\mathrm{V}}_{3}$Si in stressed state has been observed at temperatures below ${T}_{c}$. In addition, a large increase is above about 25\ifmmode^\circ\else\textdegree\fi{}K. The effect does not appear to be directly related structural transformation per se since it was both samples that transform and do not. observations are consistent with ${T}_{c}$ one degree most extensively regions sample. So far as known, these first such stress on (e.g., much 20% entropy 17\ifmmode^\circ\else\textdegree\fi{}K). Although our present understanding incomplete, density states Fermi surface stress, proposed by Weger, appears involved.
