Integration of a Fast-Scanning Calorimeter into a He-cryostat — •Daniel Gaertner, Martin Peterlechner, Christian Simon, and Gerhard Wilde — Westfälische Wilhelms-Universität Münster, Institut für Materialphysik, Wilhelm-Klemm-Str. 10, 48149 Münster

The Fast-Scanning Calorimeter (FSC), also known as Chipcalorimeter, is a power compensated and small scaled Differential-Scanning Calorimeter. Typically, sample up to several micrometers in diameter can be investigated with high heating rates exceeding 10000 K/s. Two FSC sensor chips are used simultaneously, one sensor is used as a reference and the other for the sample. Depending on the thermal bath temperature it is expected to achieve even higher cooling rates under high vacuum in a He-cryostat, the Physical-Properties-Measurement-System (PPMS, QD-LOT). Another advantage is a switchable magnetic field up to 9 Tesla. The technical approach of this custom build system will be presented including calibration procedures. The present approach allows in-situ quenching of metallic glasses, and measurements of the magnetic contribution to the specific heat of high-entropy alloys.
