Abstract:Transition-metal atoms with d electrons sometimes form clusters in crystals, which significantly affect the physical properties. Such a cluster formation frequently accompanies a change in the crystal system, leading to the presence of domains with different crystal orientations. In particular, the cubic symmetry is rarely retained after the cluster formation. Here, we identify a cubic-to-cubic phase transition in lacunar spinel GaNb 4 Se 8 , where the change in the lattice parameter is less than 0.0001%. Each… Show more
