摘要/Abstract

摘要： 对本征场的计算方法作了新的分析,提出了新的计算方案,根据这方案编写了程序,并应用这一程序对掺Cr³⁺铝铵矾单晶变角的EPR谱作了解析,得到了更加可靠更为准确的自旋-Hamilton参数;D=0.04845cm^-1,g_x=g_y=1.9761,g₂=1.9752.用上述参数,对各个离子不同角度下的广义本征场计算的共振磁场与实验数据拟合很好.充分说明采用此法处理EPR的优越性.

Abstract: In this paper we have proposed a new method by which the eigenfield equation can be solved more easily. A general computer programme has been written to calculate EPR spectra using this method. The programme has been applied to investigate angular variation of the EPR Cr³⁺-doped aluminum ammonium alum. The angular variation of the EPR lines for Cr³⁺ has been fitted successfully by this method. The spin-Hamittonian parameters were obtained:
D=0.04845cm^-1, g₂=1.9752 g_x=g_y=1.9761
This example fully illustrates the utility of the eigenfield method.

Key words: Eigenfield, EPR of Cr³⁺
