EuCu2(Ge1-xSix)2 : from mixed valence to stable moment excitation spectrum
An inelastic neutron scattering experiment is proposed to study magnetic excitation spectra of representative EuCu2(Ge1-xSix)2 samples. These sytems provide the possibility to... -
Spin-orbit coupling and spin dynamics in hexagonal iridate
Hexagonal iridate Na2IrO3 has recently been proposed as a candidate material to exhibit strong spin-orbit coupling effects which may stabilize a Mott insulating state with...
