Unconventional Magnetism in a Nitrogen-Containing Analog of Cupric Oxide
Unconventional Magnetism in a Nitrogen-Containing Analog of Cupric Oxide
We have investigated the magnetic properties of CuNCN, the first nitrogen-based analog of cupric oxide CuO. Our muon-spin relaxation, nuclear magnetic resonance, and electron-spin resonance studies reveal that classical magnetic ordering is absent down to the lowest temperatures. However, a large enhancement of spin correlations and an unexpected inhomogeneous magnetism …
