我们给出了n型InP的传导-电子自旋共振（CESR）数据。由于运动变窄，已经观察到相当尖锐的CESR信号，这使得人们可以研究由于$^{115}\ maththrm {In}$原子核的平衡和动态核极化而引起的CESR线的移动。动态极化后的核极化单指数恢复到热平衡，给出了$^{115}\数学{In}$弛豫时间：${T}_{1}^{(N)}$=450 s在3.5 K。此外，通过对样品进行额外的射频辐照，测量了CESR信号的位移，得到了$^{115}}{In}$核磁共振。
We present conduction-electron spin resonance (CESR) data on n-type InP. Owing to motional narrowing, quite sharp CESR signals have been observed, which allows one to study shifts of the CESR lines as a consequence of both equilibrium and dynamic nuclear polarization of $^{115}\mathrm{In}$ nuclei. The monoexponential recovery of the nuclear polarization to thermal equilibrium after dynamic polarization gives a measure of the $^{115}\mathrm{In}$ relaxation time: ${T}_{1}^{(N)}$=450 s at 3.5 K. Moreover, the $^{115}\mathrm{In}$ nuclear magnetic resonance has been measured by the shift of the CESR signal under additional rf irradiation of the sample.
