G2chi.m

This function calculates a high-termperature estimate of the magnetic susceptibility tensor from the user-supplied g-tensor. Syntax:

                              chi=g2chi(g,T)

Parameters:

     g - 3x3 g-tensor matrix in Bohr magneton units

     T - absolute temperature in Kelvin

Outputs:

   chi - 3x3 magnetic susceptibility tensor in cubic Angstrom
