Title: LONG-TIME TEMPERATURE DRIFT IN A COMMERCIAL SQUID MAGNETOMETER
Author: KOPELEVICH, Y
MOEHLECKE, S
Abstract: Temperature-calibration measurements using a Pt thermometer placed into a commercial SQUID magnetometer (Quantum Design) instead of the sample have shown a long-time(greater than or equal to 8 h) temperature drift occurring in a SQUID body. It is found, that the amplitude of this drift depends on the measuring set temperature. We present also results of the mixed-state magnetic-moment measurements as a function of time and field performed on Bi2Sr2Ca2Cu3O10 high-T-c superconductor, which illustrate that the magnetometer temperature drift essentially modifies the true magnetization behavior.
