On the Thermal Conductivity of Magnets near the Point of Phase Transition

Gladkov SO

An estimate of the thermal conductivity coefficient of ferromagnetic κ at temperatures lying near the point of phase transition, i.e. at temperature T = T_c −ε , where ε <<T_c . made. The calculations are based on the quasi-classica kinetic equation method, and it shows that

with a critical index equal and where H_a − field of magnetic anisotropy, H_E − exchange field.
