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... -
Temperature Dependence of the Magnetic Excitations in Ni-doped NaFeAs
In a recent work by Jun Zhao's group [Nature Communications 7, 12182 (2016)], they show that FeSe exhibits both stripe (1,0) and Néel (1,1) antiferromagnetic order, with the... -
Spin waves in as-grown PLCCO-- How doping without annealing affects the spin ...
We propose to study the spin wave excitations of nonsuperconducting single crystal Pr0.88LaCe0.12CuO4 (PLCCO). Previous experiments on superconducting PLCCO have shown that spin... -
Spin wave in Nd2CuO4-- Determination of the magnetic exchange couplings of th...
Since the discovery of high transition temperature (high Tc) copper oxide, many efforts have been made on the understanding of its electronic and magnetic properties. Although... -
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...
