Semiempirical expression for the paramagnetic susceptibility of LuFeO3 and KMnF3 by the Padé approximant

Research output: Contribution to journalArticlepeer-review

Abstract

Padé approximant to the high temperature susceptibility series expansion for a simple cubic antiferromagnet with nearest and next nearest neighbour interactions is compared with the experimental results for LuFeO3 and KMnF3. It is found that the [2,1] Padé approximant to the susceptibility series is in better agreement with the experimental data than the series expansion, in the region T/Tc < 2.
