muSR of a Quantum Spin Liquid based on the Hyperhoneycomb Lattice
The hyperhoneycomb lattice can be viewed as a 3D version of the 2D honeycomb and the new magnetic compound [(C2H5)3NH]2Cu2(C2O4)3 provides a rare example. Honeycomb type... -
Vibrations of a muoniated radical center and photochemistry in benzophenone
Benzophenone is an ideal material to study vibrations of a muon radical centre with near-IR laser light, as all C=O bonds in solid state are almost parallel to each other and it... -
