Spin Wave Dispersion in BaFe2As2
Understanding the magnetic exchange coupling and fundamental Hamiltonian of the parent compound of FeAs-based superconductors is extremely important, because such information... -
Slow magnetic fluctuations and superconductivity in CeRhIn5 at ambient pressu...
CeRhIn5 is an antiferromagnetic itinerant magnet which illustrates a temperature and pressure interplay between antiferromagnetism and superconductivity. Recently, it has been... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
The search for long range exchange interactions in the S=1 square lattice ant...
Exchange interactions in insulators can be understood in terms of the Andersen exchange picture in which the Hamiltonian has two contributions: (i) a kinetic term characterized... -

Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their... -
Spin and orbital fluctuations in MgV2O4
We propose to the measure the spin and orbital fluctuations associated with Vanadium in MgV2O4 using the MAPS direct geometry chopper spectrometer. This proposal will use the... -
Study of frustration and the anomalous Hall effect in Fe3Sn2
We have found unusual and promising Hall effect behaviour in the alloy Fe3Sn2 at 300K. Fe3Sn2 is predominantly ferromagnetic, however, our neutron diffraction data indicate that... -
