Susceptibility of compressible Heisenberg ferromagnet

Research output: Contribution to journalArticlepeer-review

Abstract

The spin-phonon spin 1 2 Heisenberg system is found to have the same critical index for the susceptibility as the ideal, rigid lattice ferromagnet. This is in accordance with the criterion for critical index renormalisation expounded by Fisher in terms of the sign of the specific heat index.
