We study the magnetic transition and spin correlation in Mn oxides at low temperatures. The results indicate that there are antiferromagnetic (AF), spiral (SP), ferromagnetic (FM) and canted (CN) states when T → 0. With temperature increasing, a paramagnetic (PM) state appears. The spin–spin correlation function is also obtained.

The Scaling Function

An extension of the analytic regularization technique based on the conform 1 theory is suggested for the case of the spin-spin correlation function of the Ising model in a magnetic field, <σ0σR>h=F(t)/(R)1/4, t=hR15/8. Several first terms of the expansion of the scaling function F(t) are given.
