13. A remanent magnetic field is usually positive in a superconductor due to the trapped flux. But this trapped positive field in the superconducting solenoid could lead to a negative field of the order of 10 G in the sample space. This can cause error due to a finite dM/dH. In our experiments, Pd standard was measured subsequently and the results shown in the insert of Fig. 1 was after the field correction. However, we are not absolutely sure if such a correction is sufficient due to the remaining field error of about 1.5 G in our set-up and a large dM/dH for the sample than the Pd standard.
