[en] This work describes the design and realisation of an apparatus to measure simultaneously the AC magnetic properties and the temperature distribution on the top surface of bulk superconducting samples (up to 32 mm in diameter) in cryogenic conditions (temperature range 78-120 K). First we describe the experimental set-up used for simultaneous thermal and magnetic characterization of the sample. Next we describe the practical considerations required for generating the large AC magnetic fields, possibly in the presence of DC fields. In the third section we present a custom-made high speed data acquisition system for replacing the laboratory devices (DC voltmeter and AC lock-in amplifiers) when both temperature and magnetic data need to be recorded at high a sampling rate. The performances and limitations of the system are discussed.
