Abstract
Paramagnetic susceptibility and spin-density correlation function near the Curie temperature TC are studied using the dynamic spin fluctuation theory. The calculated critical indices of the susceptibility and correlation radius for Fe, Co, and Ni are found in reasonable agreement with bulk susceptibility measurements and neutron scattering experiments. It is shown that the critical power-law behavior holds at temperatures up to 1.10–1.15TC, which gives an estimate of the critical temperature region in ferromagnetic metals.
