Dielectric Measurements

Dilatometry

  • Capacitance

  • Fiber-Bragg

  • Piezo

A capacitive dilatometer measures a change of sample dimension by monitoring the capacitance between two parallel plates.

Phase transitions that produce small length changes (even on the order of nanometers) due to thermal expansion or magnetostriction can be resolved by making contact between the tip of a miniature piezo-resistive cantilever and a sample.

Electrical Transport

  • AC Electrical Conductivity

  • Contactless Conductivity

  • DC Electrical Conductivity

  • High Current and Jc

The user can place small samples into an inductor (i.e., coil) of an LC tank circuit oscillating at a resonant frequency.
