The magnetic H - T phase diagram of a quasi-two-dimensional antiferromagnet RbFe(MoO4)2 with an equilateral triangular lattice structure is studied with 87Rb NMR and neutron diffra…
Antiferromagnetic Switching Driven by the Collective Dynamics of a Coexisting Spin Glass
Eran Maniv, Nityan Nair, Shannon C. Haley +11
The theory behind the electrical switching of antiferromagnets is premised on the existence of a well defined broken symmetry state that can be rotated to encode information. A spi…
Anomalous 140 K electronic transition in BiSe: Possible charge order in a defect-engineered system
