Abstract

We present a comparative study of the magnetic and crystal chemical proper-ties of two Co2+ containing garnets.CaY2Co2Ge3O12 and NaCa2Co2V3O12 both exhibit the onset of antiferromagnetic order at 8 K and 6 K as well as field-induced transitions around 7 T and 10 T, respectively that manifest as anomalies in the dielectric properties of the material. We perform detailed crystal-chemistry analyses and complimentary density functional theory calculations to show that very minor changes in the local environment of the Co-ions explain the differences in the two magnetic structures and their respective properties.
