Abstract:The magnetic behaviour of very dilute 57Fe(≈20 ppm) impurities in paramagnetic NixRh1?x (x = 0.42 and x = 0.55) alloys has been studied by Moessbauer spectroscopy in the temperature range between 11 and 0.05 K and in external fields up to 5.6 T. The magnetic moment associated with the Fe-impurity is determined via the dependence of the hyperfine magnetic field on applied magnetic field and temperature. Below 4.2 K deviations from a free spin behaviour are found. The saturation hyperfine field becomes dependent on the applied field, a behaviour which is typical for impurity spin compensation. This compensation decreases with Ni concentration.
