摘要：

SQUID magnetometer measurements of the magnetic susceptibility (χ║and χ┴) of MnF2have been carried out in the temperature interval 4.2 to 300 K, with special emphasis paid to the region in the immediate vicinity of the Néel point. By combining our data with specific heat data from Teaney (Phys. Rev. Lett. 14, 898, 1965) we have checked the validity of Fisher's relation between the magnetic specific heat Cmand the magnetic parallel susceptibility χ║. Fisher's relation state Cm/R ≃ K ∂/∂T (χ║T). © 1979 IOP Publishing Ltd.
