Pressure dependence of the spin susceptibility in vanadium

Pressure dependence of the spin susceptibility chi spin in vanadium is calculated within the framework of the local spin density approximation. It is found that the change in chi spin due to pressure is mainly caused by the change in the density of states at the Fermi level; the contribution from the change in the exchange-correlation integral is very small. The calculated result is compared with experiment by using a simplified model for the volume dependence of the orbital susceptibility.
