Applications

Keep up with the cutting edge

Significant recent research effort has been spent investigating the electronic and magnetic properties of materials when subjected to uniaxial strains because it allows a convenient way to compare experimental results with structure/property relationships predicted from theory. See Uniaxial Strain in Condensed Matter Physics.

Compatible with a wide range of probes

FC100 stress cell is the ideal component for your cryogenic measurement system -  compatible with a wide variety of different probes, including x-ray diffraction, scanning probe microscopy, optical imaging, magnetic susceptibility and electrical measurements.

Measure the force applied

A reliable cryogenic force sensor is very valuable addition to the field of uniaxial pressure tuning. Regardless of how much the mounting epoxy is deformed, the force applied to the sample will equal the force measured. This makes a force measurement independent of how the sample is mounted and hence a more reliable metric than the displacement.

Customer Requirements

For best results we recommend that customers use the cells with the following equipment;

  • A Razorbill Instruments RP100 power supply is compatible with the FC100 and all four CS1XX strain cell models. This power supply can supply low-noise four quadrant, sink/source voltages of ±200V.
  • Use of the feedback sensor requires the detection of an approximately 5 pF capacitance.  A high quality, low-cost option is the Keysight E4980AL (20 Hz to 300 kHz).
  • Suitable wiring and feedthroughs into the cryostat. The FC100 requires 4x  high voltage lines to drive the cell and 2x coax cables for the sensor. Razorbill Instruments can provide kits for adding suitable cabling and feedthroughs to a range of commercial cryostats. Please contact us for more information

Recommendations

  • Buying a FC100 stand and sample mounting table will enable easier sample mounting.
  • If you require fine electrical connections to the sample (such as in an electrical transport measurement) we recommend using a Razorbill wiring platform so that the contact pads can be situated as closely as possible to sample and these contacts can be integrated with existing wiring.
