Abstract

The structural, magnetic and electronic properties of the Ruddlesden-Popper material Sr₃CoRuO₇ have been investigated. Examination of the dc and ac magnetic susceptibility demonstrates that Sr₃CoRuO₇ exhibits a spin glass transition at 40 K and a magnetic transition at 140 K. Variable-temperature neutron powder diffraction experiments showed no evidence of magnetic diffraction peaks down to 5 K. This suggests the transition at 140 K is a result of short range magnetic order or magnetic clustering of the Co/Ru spins. Sr₃CoRuO₇ is semiconducting and Mott variable range hopping behaviour is observed below 240 K.
