Field range up to 90 T
Temperature range 0.5 ... 300 K
Sample size Any type of form. Preferably circular or square. Any thickness. 2 Samples can be measured simultaneously. The size depends on the inside diameter of the cryostats depending on the desired field value.
For 90T, the sample size should not exceed 1 * 1mm².
For 70 and 80T, the sample size can be up to 2 * 2mm².
For 60T, the sample size can be up to 4 * 4mm².
Ability to make an angular dependency up to 60T. Precision: 1 °.
Sensitivity and frequency range 0.1 ppm using TDO @ 10-50MHz
1 ppm using transmission technique @ 0.1-2GHz
Typical experiment Frequency dependence vs field
Frequency dependence vs temperature (at 0 field)
Sample Holder


Samples are glued into the Rf coil
