I want to do similar kind of measurement as shown in Fig1 of the paper. I see it was measured using capacitive Faraday magnetometer, but don't have any idea how it works?
Dear Prof. Mirgorod, Thanks for your answer, but unfortunately, that was not regarding my question. You can see I have quite a few publications on magnetism so I know the basic of ZFC/FC and MH measurements up to 2 K. My question was specifically on the measurement of MH below 1 K, which is beyond the ability of a commercial SQUID magnetometer (MPMS XL, QD). All I am sure one has to make separate arrangement in a He-3 or a dilution refrigerator.
