Constraints on the Possible Long-Range Orbital Ordering in LaCoO 3

January 1, 2014
Author(s)
Daniel P. Phelan, Peter M. Gehring
A neutron powder diffraction measurement was performed to distinguish between the proposed monoclinic (I2/a) structure of LaCoO 3, which is consistent with orbital ordering, and the rhombohedral (R3c) structure, which is inconsistent with orbital ordering

Controllable Positive Exchange Bias via Redox-Driven Oxygen Migration

March 21, 2016
Author(s)
Dustin A. Gilbert, Justin Olamit, Randy K. Dumas, Brian J. Kirby, Alexander J. Grutter, Brian B. Maranville, Elke Arenholz, Julie A. Borchers, Kai Liu
We have observed oxygen migration across buried interfaces in Gd^xdx^Fe 1-x/NiCoO films, which leads to tunable positive exchange bias over a relatively small cooling field range of 300 mT. The tunability is shown to be the result of an interfacial layer
