Magnetic properties of thin films

Anomalous electron spin resonance observed in Nd 2 CuO 4 is attributed to antiferromagnetic resonance (AFMR) of Nd spins in the Nd–Cu spin network. The anomaly comes from the staggered field due to Cu spins on the Nd-site. The Cu spins form a tight antiferromagnetic spin network and are almost at rest during the Nd-resonance. The staggered field acts as an additional anisotropy field on the Nd spin. Various magnetic parameters in AFMR are in accord with those determined by the high field magnetization study.
