Magnetic and Quadrupolar Excitations in UPd3
UPd3 exhibits four antiferroquadrupolar (AFQ) ordered phases below T0=7.6K. We have determined their order parameters using resonant x-ray diffraction. UPd3 has the dhcp crystal... -
Stationary Spin Waves in the Skyrmion Crystal
The inter-metallic B20 compound MnSi is of great interest as a magnetic model system exhibiting helical spin ordering and topologically non-trivial spin correlations. The...
