摘要： 对掺Cr³⁺乙酰丙酮铝单晶的(001),(100)和(110)晶面进行晶面旋转EPR扫描,得到共振磁场随旋转角度变化的实验图形,根据本征插方法编写的程序,对实验谱图进行投合,得到下述顺磁参数,D=0.5870±O.005cm^-1,E=-0.00490±0.0001cm^-1,g_x=g_y=1.965±0.001,g₂=1.984±0.001.

Abstract: Single crystals of monoclinic aluminum acetylacetone were grown by evaporation of saturated solutions and the structure was determined by x-ray single crytal diffraction. Angular variation of EPR spectra for chromium-doped aluminum acetylacetone were investigated. A curve was gained by eigenfield method. Which is fitted with the experimental curve very well. The paramagnetic parameters obtained via this method are:
D=0.587cm^-1 E=-0.0049 cm^-1 g_x=g_y=1.965 g₂=1.984

Key words: EPR of single crystal, Eigenfield method
