説明

Magnetic properties of (1−x)Fe2TiO3-xFe2O3 with x near the percolation threshold x∼0.2 have been studied by using single crystals. It has been found that 0.9FeTiO3-0.1Fe2O3 exhibits typical characteristics of the cluster spin glass, while 0.79FeTiO3-0.21Fe2O3 can be identified with the re-entrant spin glass. Referring to the neutron scattering data obtained for those compounds, the magnetic phase diagram has been determined. The results have been discussed based on the current theories on the concentrated spin glass systems.
