| Abstract: | The specific heat at the Jahn-Teller phase transition in DyVO4 is too sharply peaked to be explained by simple mean-field theory, but is very well described by using a mean-field model in which the effective interaction increases upon ordering according to J′=J0′(1+ζ〈σz〉2) where ζ is an adjustable parameter. |
