The Isothermal Pressure Derivatives of the Elastic Shear Modulus for V3Si
The effects of a hydrostatic pressure on the shear modulus cs and the structural transition temperature T of V3Si are studied on the basis of the coupled chain model of Gorkov Cor the model proposed recently by Lee, Birman and Williamson). Taking into account the charge transfer effect between different bands and choosing suitable values for the Fermi energies, our results can account for the temperature dependences of (∂cs/∂p)T quantitatively for transforming V3Si and satisfactorily for nontransforming V3Si.

- 16.For V3Si the structural transition is a weak first-order one, and the condition cs = o at Tm in principle can no longer be applied to determine Tm. However, in the present model more than 95% of Tm comes from cs = o for V3SL Therefore the use of Born’s stability limit to determine Tm for V3Si should be valid.Google Scholar
