本文报道了手性自旋体系CuB{sub 2}O{sub 4}在35 GHz的H平行c. c轴的g值确定为2.16。在21和9 K附近观察到共振场和线宽的异常，这对应于连续的相变。在螺旋磁共振态，除了螺旋磁共振吸收外，ESR谱中还出现了一个小的滞后凹陷。当温度低于9 K时，随着温度的降低，下降迅速向高场移动。
We report ESR measurements of the chiral spin system CuB{sub 2}O{sub 4} at 35GHz in H parallel c. The g-value is determined as 2.16 for the c-axis. Anomalies in the resonance field and the line width have been observed around 21 and 9K, which correspond to the successive phase transitions. In the helimagnetic state, a small hysteretic dip appears in ESR spectrum in addition to a helimagnetic resonance absorption. The dip shifts rapidly to the higher field with decreasing temperature below the transition temperature at 9K.
