The MR module lets users investigate magnetoresistive and ferroic materials. The system can be fitted with various electromagnets for this purpose. Just like the RS module, the MR module features a high-precision power source. The drop in voltage across the sample is measured using highly accurate four-point measurement, together with an electrometer amplifier. This makes it possible to measure 10 mOhm, for example, with a precision of better than 1%. As a result, users can measure magnetic tunnel junctions, Josephson junctions, etc.
