What is the magnetic susceptibility of a particular material at different temperatures and how does it vary with temperature? Can you explain the underlying physical mechanism for this temperature dependence? Additionally, can you use this information to predict the critical temperature at which the material undergoes a phase transition and changes from a paramagnetic to a ferromagnetic state?
