N2 - The electron spin resonance spectra of Er in PrSb and TmSb single crystals exhibit two lines with appreciable angular dependent resonance fields. The data is analysed in terms of a Lambda 8(1) crystalline field ground state together with a generalized exchange interaction between the Er ions and the host Pr (or Tm) rare earth ions. Using the crystalline field parameters as determined for the analogue compounds YSb:Er and LaSb:Er, the exchange parameters for PrSb:Er were found. Unlike previous predictions, no evidence for a significant orbital anisotropy in the exchange was observed.
