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... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
Unprecedented strong superexchange through one atom for a Ag(2+)-based 1D ant...
We propose to investigate AgFBF4, compound known for > 20 years, with inelastic neutron scattering. The scope is to determine the value of J for this Ag(2+)-based 1D... -
Spin-orbit transitions of Co3+ in LaCoO3
In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of... -
Electronic state of Co3+ in LaCoO3
We will search for spin-orbit transitions of the Co3+ ions in LaCoO3. The ground state is a non-magnetic singlet, but there continues to be a debate about the nature of the... -
Intra-block magnetic excitations in KFe0.8Ag1.2Te2
KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A...
