| Abstract: | Magnetic properties of nine RE2Au compounds have been studied in fields of up to 19 kOe in the temperature range 4.2K–300K. It has been found that all compounds are paramagnetic at room temperature except Gd2Au. The compounds with Pr, Nd, Ho, Er and Tm exhibit Curie-Weiss behaviour with paramagnetic moments in close agreement with those expected for the free RE3+ ion. The moment of gold was found to be zero. The compounds with Pr, Nd, Tb, Dy, Er and Tm are antiferromagnetic at low temperatures. It appears that Ho2Au is ferromagnetically ordered below 4.5 K. No evidence for magnetic ordering was found for Y2Au. The compound with Tb exhibits metamagnetic behaviour. |
