Electronic Structure and Bulk Spin Valve Behavior in Ca3Ru2O7
D. J. Singh, S. Auluck
Abstract
We report density functional calculations of the magnetic properties and Fermiology of Ca3Ru2O7. The ground state consists of ferromagnetic bilayers, stacked antiferromagnetically. The bilayers are almost but not exactly half-metallic. In the ferromagnetic state opposite spin polarizations are found for in-plane and out-of-plane transport. Relatively high out of plane conductivity is found for the majority spin, which is relatively weakly conductive in-plane. In the ground state in-plane quantities are essentially the same, but the out of plane transport is strongly reduced.
