Abstract

Magnetic susceptibility and powder neutron diffraction results are reported on the cubic spinel Co₂RuO₄. These measurements indicate spin-glass formation in this compound, with a freezing temperature of about 16 K. Magnetic susceptibility results are also reported on ZnCoRuO₄, a spinel in which only the Ru³⁺ ions are magnetic. No magnetic order was found in ZnCoRuO₄ down to 2 K, indicating extremely weak interactions between the octahedral Ru³⁺ ions in these materials.
