Research Interests
Magnetism and superconductivity in a variety of materials systems as investigated using neutron scattering techniques; elastic NS to study lattice and magnetic structures and transitions, and inelastic NS measurements to provide detailed information on lattice and spin dynamics. Materials systems studied include giant magnetostrictive, martensitic/shape memory, magnetocaloric, high-temperature superconducting Fe-pnictide and magnetoelectric.
