N2 - Mössbauer studies of the 84.3 keV gamma ray of Yb170 emitted from Yb in TmxHo1-xFe2 at various temperatures were performed. These yield the crystalline field parameters (A4〈r4〉 = 36 ± 5 K, A6〈r6〉 = -3 ± 2K, the exchange field (μBHexch = 116 ± 4 K) and the Yb3+ free ion hyperfine constants (H4f = 4100 ± 150 kOe, eqQ = 2400 ± 250 MHz and H (conduction electrons) = 350±100 kOe). Spin relaxation phenomena observed in TmFe2 at low temperatures give a value of ∼ 0.03 for |ρ{variant}(EF)Jsf|. Spectra observed in Tm0.2Ho0.8Fe2 in the spin reorientation transition region indicate that the transition is of second order.
