Contactless Conductivity in DC Fields

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

By measuring changes in the frequency, we can detect changes in the penetration depth of a superconductor, the susceptibility of a magnetic system or the surface conductivity of a metal. The absence of contacts connected to the sample allows this technique to produce less strain than conventional transport for fragile samples.
