Electrical Transport and Rotation...

ETO Training
- Sample mounting / Setting up measurements
- Interpreting the data
- Quantum Design training seminars (longer)
FastHall M91 Training
- seminar on FastHall from LakeShore:
Use Case Examples (users, please contribute to these!)
- Si Hall mobility.pdf : example of Hall effect and van der Pauw resistivity measurements to determine mobility of p-type silicon.
- ETO Training Report_Cadiente.pdf : using ETO to measure superconducting Tc and Hc2 of Nb metal film.

Use Case Examples (users, please contribute to these!)
- Also: see example sequence folder C:\Qddynacool\Sequence\Example sequences to get you started
References
- TTO User's Manual

Heat Capacity...

Training
- Quantum Design training seminars
Use Case Examples (users, please contribute to these!)
- heat capacity of pure Au shot at low temperatures in fields up to 9 tesla
  - this demonstrated that heat capacity of Au is not field dependent and follows published data (Martin), which verifies the accuracy of our magnetoresistance correction of the Cernox on the heat capacity chip
  - report from Mohan Neupane (Arnab Banerjee lab, PHYS): Gold lowT HeatCap in field Pk3091.pdf
  - data from the run: gold HC and addenda.zip and the .cal file for puck 3091 that was used: Puck3091.cal
- Also: see example sequence folder C:\Qddynacool\Sequence\Example sequences to get you started
