Measurements of the electrical resistivity of palladium, residual resistivity ratio 22 500, containing 1.7 ppm of Fe have been made from 5.5 K to 1.8 mK. 15 Hz ac susceptibility measurements from 1 K to 1.8 mK together with the resistivity data suggest that a transition into a spin-glass state occurs near 7 mK. © 1983 The American Physical Society.
