Sublattice magnetization of antiferromagnetic MnF2
Heller and Benedek used nuclear magnetic resonance techniques to determine the critical exponent [beta] of MnF2 to unprecedented accuracy. This experiment provided important confirmation that antiferromagnets are like ferromagnets, which are in turn like fluids, thus giving impetus to the conviction that critical phenomena should encompass all these effects.
