Equipment
The equipment of the Bulk Properties Lab consists of six cryomagnets and one virtual instrument, a finite elements program (Comsol Multiphysics). The cryomagnets are equipped with different measurement options and cover the temperature range from 10 mK up to 1000 K at magnetic fields up to 17 T.

|---|---|---|---|---|
| CM-14.5T | 14.5T Cryomagnet with VTI or 3He Stick | 14.5T | 0.28K..300K | |
| PPMS-14T | Physical Properties Measurement System (Quantum Design) | 14T | 1.8K..400K (1000K) | |
| PPMS-9T | Physical Properties Measurement System (Quantum Design) | 9T | 1.8K..400K | |
| MPMS-5T | Magnetic Properties Measurement System (Quantum Design) | 5T | 2K..800K | 5mm diameter |
| MPMS-VSM-7T | Magnetic Properties Measurement System VSM (Quantum Design) | max 7 Tesla | 1.9 K - 1100 K | typical 1*1*1 mm^3 |
| CM-17T | 17T Cryomagnet with 3He/4He Dilution Refrigerator resistivity measurements and magnetization measurements for very friendly users | 17 T | 10mK..10K | |
| Comsol Multiphysics | Finite element simulation software and hardware. | |||
| Custom | Customized Experiments using various Equipment of the Sample Environment Department | 14.5T | 30mK - 2000K | different |
The user measurements can be performed in two modalities: "ordered measurements" and "own measurements". An ordered measurement will be performed by a member of the Bulk Properties Lab staff, the presence of the proposer of the measurement is not necessary. For some of the measurement options this is the only possible choice because of the complexity of the experiments. For example this is the case for all measuremets at CM-14.5T or CM-17T. Other experiments can and should be performed by the proposers themselves ("own measurement"). For unexperienced users, the Bulk Properties Lab instrument responsibles will give a detailed introduction on the instruments and will provide assistance during the measurements.
