Query: Ferromagnetic phase transition in a Heisenberg fluid: Monte Carlo
  simulations and Fisher corrections to scaling   The magnetic phase transition in a Heisenberg fluid is studied by means of
the finite size scaling (FSS) technique. We find that even for larger systems,
considered in an ensemble with fixed density, the critical exponents show
deviations from the expected lattice values similar to those obtained
previously. This puzzle is clarified by proving the importance of the leading
correction to the scaling that appears due to Fisher renormalization with the
critical exponent equal to the absolute value of the specific heat exponent
$\alpha$. The appearance of such new corrections to scaling is a general
feature of systems with constraints.
