Excitations in an orbitally dimerized spin S=1 honeycomb antiferromagnet
Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold... -
Negative thermal expansion in ReO3: anomalous variation with temperature
ReO3 is a well-known oxide framework with unusual thermal expansion behaviour, exhibiting multiple regions of both positive and negative thermal expansion (NTE). We propose to... -
Phase Separation in NaTaO3. Can it be controlled by pressure?
The present proposal seeks to establish the pressure dependence of the Pbnm-Cmcm transition in NaTaO3 and some doped variants thereof. It aims to understand the understand the...
