To identify and report a new type of phase transition in averievite-related compounds.
Investigated temperature-dependent behavior of averievite compounds.
Examined various compositions including CsBr, CsI, RbBr, RbI, and KI.
A previously unrecognized type of phase transition was identified.
Findings suggest subtle symmetry breaking in the structure of these compounds.
Abstract
In this work, we report a previously unrecognized type of phase transition within the averievite family of compounds, ( MX )Cu 5 O 2 (VO 4 ) 2 ( M = Cs, Rb, K; X = I, Br). Using temperature-dependent...
