摘要

用改进的双光学共振方法测量了金刚石中氮空位(NV)色中心的氮-14原子核自旋纵向弛豫时间。该金刚石样品采用高温高压法生长，含有1ppm的nvcentre。纵向弛豫时间为43(6)s，与色心电子自旋与声子和自旋储层相互作用的弛豫模型计算的时间进行了比较。测量的时间与模型的预测一致。

Measurement of the longitudinal relaxation time for the nitrogen nuclear spin in a nitrogen-vacancy colour centre of diamond

A longitudinal relaxation time of a nitrogen-14 atom nuclear spin for a nitrogen-vacancy (NV) colour centre in diamond is measured by the modified double optical resonance method. The diamond sample was grown by the method of high temperature and pressure and comprised 1 ppm of NVcentres. The longitudinal relaxation time was 43(6) s, which was compared to the time calculated in the model of relaxation due to the electron spin of colour centre interaction with phonons and spin reservoir. The time measured well agrees with predictions of the model.
