Evolution from long-range order to spin glass state in Heisenberg antiferromagnetic alloys of γ-Fe

Magnetic measurements, neutron diffraction and the μSR method were used to investigate the reentrant temperature transitions in the Heisenberg frustrated antiferromagnetic Fe x Ni 80- x Cr 20 and Fe x Ni 80- x Mn 20 alloys. It was shown that for the alloys whose concentrations are close to the onset...

Description
Summary:Magnetic measurements, neutron diffraction and the μSR method were used to investigate the reentrant temperature transitions in the Heisenberg frustrated antiferromagnetic Fe x Ni 80- x Cr 20 and Fe x Ni 80- x Mn 20 alloys. It was shown that for the alloys whose concentrations are close to the onset of the long-range antiferromagnetic order, the following succession of transitions is observed under cooling: paramagnet - collinear antiferromagnet (antiasperomagnet) - reentrant spin glass. There is no long-range antiferromagnetic order in the reentrant spin glass phase but the antiasperomagnetic correlations with finite correlation length are present.
