On-chip SQUID measurements in the presence of high magnetic fields

Résumé

We report a low temperature measurement technique and the magnetization data of a quantum molecular spin, by implementing an on-chip SQUID technique. This technique enables SQUID magnetometry in high magnetic fields, up to 7 T. The main challenges and the calibration process are detailed. The measurement protocol is used to observe quantum tunneling jumps of the S = 10 molecular magnet, Mn12-tBuAc. The effect of a transverse field on the tunneling splitting for this molecular system is addressed as well.
