Abstract
We present the magnetic properties of complete solid solutions ofZnCr2O4 andCoCr2O4: two well studied oxide spinels with very different magnetic ground states.ZnCr2O4, with non-magneticd10 cations occupying theA site and magnetic d3 cations on the B site, is a highly frustrated antiferromagnet.CoCr2O4, withmagnetic d7 cations (three unpaired electrons) on the A site as well, exhibits Néel ferrimagnetism as wellas commensurate and incommensurate non-collinear magnetic order. More recently,CoCr2O4 has been studied extensively because of its polar behavior which arises fromconical magnetic ordering. Gradually introducing magnetism on the A site ofZnCr2O4 results in a transition from frustrated antiferromagnetism to glassy magnetism at lowconcentrations of Co, and eventually to ferrimagnetic and conical ground states at higherconcentrations. Real-space Monte Carlo simulations of the magnetic susceptibility suggestthat the first magnetic ordering transition and features of the susceptibility acrossx are captured by near-neighbor self-couplings and cross-couplings between the magnetic Aand B atoms. We present, as a part of this study, a method for displaying the temperaturedependence of magnetic susceptibility in a manner which helps distinguish betweencompounds possessing purely antiferromagnetic interactions from compounds where otherkinds of ordering are present.
