Notes:
Our ac susceptibility (χ) measurements, carried out between 1.7 and 100 K, show five χ peaks, signaling five transition temperatures, in the disordered frustrated spinel ferrite Co2TiO4. This result, in conjunction with the replica symmetric mean field theory of vector spin glasses and earlier magnetization and neutron diffraction studies, indicates a separate freezing of A- and B-site spins. To our knowledge, such a phenomenon has not been observed before. Co2SnO4 and Co1.2Zn0.8TiO4 χ measurements, where three and one χ peaks are respectively observed, support this picture.
