Summary

Anomalies of sound velocity and attenuation, as well as of heat capacity are revealed for the lead-stabilized bismuth ceramics of the composition 2-2-2-3 at near 60 K, which is considered as the second-order phase transition. The sensitivity of the anomalies to the quenched magnetic flux is indicative of the magnetic nature of the transition. Similar features are also observed at the same temperature in the 1-2-3 type superconducting systems.
