SmN and DyN: Effect of the nitrogen to rare earth flux ratio on the structural, transport, and magnetic properties

We report on the effect of nitrogen to rare earth (N2/RE) flux ratio structural, transport, and magnetic properties samarium nitride (SmN) dysprosium (DyN) thin films. Both materials display a reduced lattice constant when N2/RE decreases, i.e., with increased vacancies (VN) concentration. The films show several orders magnitude increase in electrical resistivity ratio. Finally, measurements DyN deviation from free ion moment at low temperature, which is eased more conductive This was interpreted as further reduction quenching orbital angular momentum caused by VN Curie temperature also found VN.
