Abstract
We have simulated a fluid of particles which carry a Heisenberg spin and interact via a Heisenberg-like interaction. The fluid displays a magnetic order-disorder transition, which we studied by varying the temperature at a fixed particle density. We located the transition and estimated critical exponents by means of a finite-size scaling analysis. The exponents differ by a small but significant amount from the ones for the lattice Heisenberg model. © 1996 The American Physical Society.Keywords
