Gaps in the spin wave dispersion relation in elemental iron
Iron is a canonical instance of an itinerant electron ferromagnet, and a classic correlated electron system. Our recent data from MAPS contradicts earlier triple-axis data that... -
Inelastic Spectroscopy of the Mobile Phase of Ammonia Borane
Ammonia borane (AB) is one of the most promising hydrogen storage materials. There has recently been work on a more mobile phase of AB (denoted AB*) which is formed (via the... -
1D Spin-1/2 Chain Dispersion of Magnetoelectric CuO
We propose to measure the high energy magnetic dispersion of CuO. At high energies, CuO exhibits quasi-1D spin-1/2 chain magnetic behaviour. Our previous studies have revealed... -
Study of hybridization gap formation in a single crystal of the heavy-Fermion...
The solution of the Anderson lattice model (ALM) leads to two renormalized bands near EF with an energy gap due to hybridization between the 4f- and conduction electrons. The... -
Probing the temperature dependence of magnetism in Ba0.67K0.33Fe2As2
We propose to study the temperature evolution of magnetic excitations in optimal doped Ba0.67K0.33Fe2As2, this work will complement our earlier work on the samples at base... -
Hourglass dispersion in overdoped manganites
Overdoped manganites were recently shown to exhibit stripe-like ordering of charges orbitals and magnetic moments. The magnetic excitations in these materials show close...
