Unformatted text preview: have a “staggered magnetic feld” which equals B on one sublattice and B on the other. Defne a “staggered susceptibility” which equals ( ∂M/∂B ) B =0 , where M is the magnetization on one oF the sublattices. Show that in the mean feld approximation, this staggered susceptibility diverges as T approaches the Neel temperature T N From above, with temperature dependence 1 / ( TT N ). 4. Pathria, Problem (11.12) (20 pts.). Skip the sentence beginning “±urther show that. ..” Also, fnd the critical temperature at x = 1/2 in terms oF the interaction parameters ǫ . 1...
