摘要：

The absorption spectra of HoFeO3 were investigated in the near infrared spectral region at temperatures of 1.2, 4.2, 20 and 77 °K respectively. At every temperature T≦20 °K all the absorption lines show the same splitting which is attributed to the groundstate; this splitting is (7.2±0.5) cm-1 at 20 °K and decreases to (4.9±0.8) cm-1 extrapolated to 0 °K. From these splittings the holmium-iron and the holmiumholmium interactions can be deduced. Measurements with an external magnetic field yield a magnetic moment of μ=(7.6±0.7)μB per holmium ion. The moments are directed at angles of -28° and -152° with respect to the b-axis. © 1969 Springer-Verlag.
