Significant Atomic Displacement at Isostructural Transition in Li_0.99Cu_0.01CrO₂ and its Effects

Abstract:

LiCrO₂ is a triangular lattice antiferromagnetic compound exhibiting geometrically frustrated two dimensional arrangement of Cr ions with T_N = 62 K at which an isostructural transition occurs. We show, using temperature dependent high energy synchrotron X-ray diffraction studies, that upon a nominal 1% Cu doping at the Li site, there are large changes in structural parameters and the (coupled) magnetic and dielectric properties.
