Muon spin-relaxation probe of chiral spin-liquid state in YBaCo4O7
Geometrically frustrated antiferromagnets RBa(Co/Fe)4O7 (R=rare earth or Y) exhibit a weak ferromagnetic component in the high-temperature spin-liquid phase. Based on a symmetry... -
In-situ neutron study of Oxygen absorption in YBaCo4O7+δ
A recent addition to the list of emergent materials is the ReBaCo4O7+delta family of compounds. Indeed, due to the magnitude of their oxygen uptake and release capability, they...
