Ferromagnetic Heisenberg Model

  1. Aug 21, 2015 #1
    Now after applying and removal magnetic field H=0 there will be residual magnetic domain in XYZ directions
    Is the Heisenberg Model at very low temperature express about the energy of the system with higher accuracy than Ising Model in the previous case ?
    and at high temperature is the Ising Model express about the energy of the system with higher accuracy than Heisenberg Model?
    is the temperature a limitation for applying Heisenberg Model in ferromagnetic material ?
    is the most convinient for temperature Ising Model?

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

    Now at what temperature can we apply Heisenberg model to ferromagnetic material
    in other words is the localized electrons (where Heisenberg model can be applied) at very low temperature or not in ferromagnetic material?

    is there a relation between localized electrons and temperature in Ferromagnetic material ?
    I ask because we can apply Heisenberg model to materials with localized electrons
