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... -
Investigation of Bose-Einstein condensation of magnons through temperature-fi...
YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down...
