Low energy excitations in PrPtAl
Magnetically modulated structures have been predicted to form close to quantum critical points in a number of recent theories, although there are no experimental examples of... -
Spin dynamics in the extended Kagome system YBaCo4O(7+x)
A recently discovered new class of geometrically frustrated magnets is the family of cobalt oxides RBaCo4O7 (R=rare earth or Y). The structure is built up CoO4 tetrahedra which...
