Description
Field range 35T
Temperature range 20K -> 1.3K (extension planned)
Sample size max: 1.5mm width and length, less for thickness to avoid inhomogeneous field within sample (500µm), single crystals (in case of anisotropy of the crystal, measurements are only possible with field along the easy axis, otherwise the torque will change the capacitance as well as the longitudinal movement, difficult to disentangle both contributions)
Sensitivity 5*10-7 emu (improvements ongoing), capacitive measurement
Typical experiment M(H), anomalies or quantum oscillations, absolute values of M only with subsequent calibration measurements
Sample Holder CuBe sample platform, single crystals attached by apiezon grease prototypes available, further improvements under construction
Sample environment exchange gas (He)
