Description
NaCu2O2 is regarded as an S = 1/2 zigzag chain with competing nearest neighbor and next nearest neighbor exchange interactions. The spin structure of NaCu2O2 below a Neel temperature TN = 13 K was reported to be helical with a propagation vector q = (0.5, 0.227, 0). To obtain further information on the ordered state of NaCu2O2, we performed multi-frequency electron spin resonance (ESR) and high field magnetization measurements on single crystal samples of NaCu2O2. We observed a large and some small ESR signals and a monotonical increase of magnetization with a change of the slope around 20 T. One of the ESR resonance modes from the large signal is roughly reproduced by one of the helical resonance modes calculated on the assumption of a conical spin structure
