Low-temperature nuclear orientation of CeNi2Al5 and CeNiSn

Abstract Hyperfine interactions at Ce sites of CeNi 2 Al 5 and CeNiSn single crystals were investigated by means of the low-temperature nuclear orientation of the 141 Ce isotope. From the temperature dependence of γ-ray anisotropies the hyperfine fields at Ce nuclei in CeNi 2 Al 5 and CeNiSn were deduced as 92 (±6) T and
