26. Interestingly, because spin 3/2 holes lead to a lower (formula presented) than spin 1/2 holes, the magnetization curves for spin 3/2 holes using the distribution (formula presented) overlap almost perfectly with the numerical mean field theory (with spin-1/2 holes) for all T.
27. It may appear from the equation for (formula presented) [Eq. (10)] that we should fit the r.m.s. exchange coupling. This would lead to minor modifications to (formula presented) however, the significant difference in shape of (formula presented) curves cannot be rectified by adjusting (formula presented)
28. The same quality of fit is seen for (formula presented) or (formula presented).
