Measurements of electron magnetic resonance are discussed for impurity ions in the antiferromagnetic host compound DyPO 4 (Néel temperature T N = 3.39 K). This is a simple two sublattice antiferromagnet; the impurity ions are Yb 3+ and Er 3+ , each with a Kramers doublet as the ground state. Resonance is observed at frequencies of ca . 24 and 34 GHz, and the angular dependence of the magnetic field is fitted to simple theoretical equations. Since the magnetic moments in the host lattice are ordered, the resonance lines are relatively narrow, making it possible to determine the value of the internal field acting on each impurity ion. From this, the exchange field is obtained by subtracting the value of the dipolar field generated by the ordered moments of the host ions. Some measurements have been made in the spin flop phase. The values of the exchange field are found not to conform to a simple model based on isotropic exchange interaction between the real electron spins of the lanthanide ions. Hyperfine splitting is detected from the odd isotope 171 Yb, natural abundance 14%, I = ½.

“…Hawkes and Leask (1968) from Zeeman spectra, and Blazey and Rohrer (1968) from magnetic properties have presented evidence that the ordered state is G, (in the notation of Bertaut 1963), while Mercier and Velleaud (1971) conclude from magnetoelectric measurements that the type is A,.…”

The Czochralski method is employed to synthesize crystals of compound orthoaluminates: GdAlO3, YAlO3, and LuAlO3 doped with erbium (Er3+). The crystal splitting schemes of 4S3/2, 4F9/2, 4IJ levels of Er3+ at 77 K are plotted based on an analysis of optical spectra. Stimulated emission due to a 4S3/2 → 4I9/2 transition is observed from Er3+ ions GdAlO3, YAlO3 at 77 K. Pulsed laser action at room temperature is only observed from Er3+ ions in YAlO3.
