Thermodynamic Origin of Negative Thermal Expansion Based on a Phase Transition-Type Mechanism in the GdF(3)-TbF(3) System

Multicomponent fluorides of rare earth elements (REEs—R) are phase transition-type negative thermal expansion (NTE-II) materials. NTE-II occurs in RF(3)-R′F(3) systems formed by “mother” single-component dimorphic RF(3) (R = Pm, Sm, Eu, and Gd) with a giant NTE-II. There are two structural types of...
