type II superconductor

type II superconductor

[′tīp ¦tü ¦sü·pər·kən′dək·tər] (cryogenics) A superconductor for which there are two critical magnetic fields; magnetic flux is completely excluded from the interior of the material only at field strengths below the smaller critical field, and at field strengths between the two critical fields the magnetic flux consists of flux vortices in the form of filaments embedded in the superconducting material. Also known as high-field superconductor (HFS).
