The canonical ensemble redefined - 2: Magnetic systems
Description
The mean field theory and the 1-D Ising model for magnetic systems are solved in the redefined ensemble formalism. In the mean field theory spontaneous magnetization is governed by the relation αprimesub(I)+2β=1 where αprimesub(I) is the input value of the critical exponent for the specific heat. 1-D Ising does not show any spontaneous magnetization even in microcanonical ensemble calculation.
