Magnetic Excitations in Chromium
Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron... -
Temperature dependence of the magnetic excitations in the near perfect S = 1/...
Quantum spin liquids (QSL) are novel states of matter that display exotic ground states and fractionalized excitations. In two dimensions, the most promising model system is the... -
Resonant Spin Excitation in Single Crystal of Ba0.8K0.2Fe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the... -
Magnetic Excitations of the Quantum Hyperkagome Antiferromagnet, Na4Ir3O8
We propose to investigate the hyperkagome antiferromagnet Na4Ir3O8. Here the magnetic Ir4+ ions lie on a three-dimensional network of corner sharing triangles and interact with...
