Low frequency magnetic susceptibility measurements have been performed on YbBiPt from 3 to 800 mK. In addition to the known peak at 400 mK, an anomaly exists near 120 mK. The lowest temperature feature arises from a surface phase (e.g. Bi2Pt) and is not a property of the main material. No additional features in the susceptibility are attributed to the bulk material down to the lowest temperature. © 1995.
