Pressure driven phase transitions in the magnetically frustrated layered material, Ca2Mn3O8

Abstract: Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity between magnetic ions has a triangular motif. In these magnetic materials the magnetically ordered state is often unconventional. Calcium manganese oxide, Ca2Mn3O8, exhibits managnese oxide layers seperated by calcium ions. Within the layers a complex "bow-tie" like connectivity of the maganese leads to a "two up two down" spin arrangement below a temperature of approximately 50 K. We would like to conduct new experiments as a function of applied pressure and temperature to extend these initial studies. This will allow us to correlate applied pressure with chemical pressure to target new frustrated materials.
