The absorption spectrum of single crystals of ErFeO has been investigated in the red and near infrared spectral region in the temperature range between 1.2 °K and 4.2 °K and at 20 °K and 77 °K. Between 77 °K and 4.2 °K a constant splitting of the absorption lines is observed. Below the Néel-temperature of the erbium sublattice at 4.5 °K the splitting of the absorption lines increases; the saturation value extrapolated to 0 °K of the splitting of the lowest crystal field level of the I groundterm is (6.08±0.30) cm. By measuring the Zeeman effect the groundstate magnetic moment is determined as μ=(6.6±0.2) μ. The measured temperature dependence of the splitting of the lowest crystalfield level of theI groundterm is compared with that calculated by a Monte Carlo method. [ABSTRACT FROM AUTHOR] |
