摘要：

The pressure effect on the magnetic susceptibility of Ni3Al and TiCo compounds is studied in the temperature range 20-293 K. The obtained magnetovolume effect values dln chi/dln V and results of detailed theoretical calculations of density of states at the Fermi level as a function of the lattice constant were used to evaluate volume derivatives of the electron-electron interaction parameter J: dln J/dln V = -0.9 +/- 0.15 (Ni3Al) and -0.95 +/- 0.15 (TiCo). These results are compared with theoretical estimates of dln J/dln V from ab initio LMTO band structure calculations.
