| 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) |
