摘要：

We present a new photoacoustic-like detection technique which allows for the rapid detection of small periodic temperature variations induced by small periodic adiabatic magnetic field variations imposed on a magnetic material. Results are presented for gadolinium near the Curie point. From the results for the periodic temperature variations of the sample information can be obtained about the magnetic equation of state.
