The reentrant spin glass properties of Ni77Mn23 were investigated by measuring the neutron polarization P(λ) as a function of the wavelength (3-9 Å). By analyzing the temperature dependent local induction from the oscillating behavior in P(λ), we found some evidence that supports the idea of domain-anisotropy model and the mean field spin freezing picture in each domain.
