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).

According to the Ginzburg-Landau theory, a rotating disk of type II superconductor at the phase transition with low temperature (e.
Suggesting all types of scalar fields to be similar in physics and addable, we obtain the total scalar field in or around a type II superconductor,
To quantitatively study the gravitational field shielding by the Ginzburg-Landau scalar field along with the Earth scalar field, we plot in Figure 2 the weight relative loss of the sample or the gravitational field relative change at the sample as a function of the temperature of the type II superconductor.
For a rotating disk of type II superconductor, the acceleration of inertially moving cooper pairs in the superconductor is equivalent to a gravitational field, which may couple with the Ginzburg-Landau scalar field to produce an extra shielding effect on gravity as shown in [21].
It argues that under these conditions the inhomogenous states appear in antiferromagnets, similar to the intermediate state of type I superconductor or the mixed state in type II superconductor.
Therefore in the type II superconductor, a superconductor domain can be as small as one molecule of superconductor material or composed of a multitude of molecules (i.
This is especially true with the type II superconductor, which exhibits flux pinning throughout the body of the superconductor and allows for flux motion during phase transition.
Since experimentally, the formation of vortices does occur during spontaneous symmetry breaking phase transitions of coupled domains in the Type II superconductor, Lorentz symmetry is violated.
Although, a theory that connects the GL scalar field to gravity has yet to be presented, here the general formulation for calculating gravitational radiation from quadrupolar motion [43] is used to illustrate the possible energy radiated in a gravitational wave from the instantaneous power flow through a type II superconductor.
However, in a type II superconductor, flux lines can shift in position, or "creep," interfering with supercurrent flow.
In type II superconductors, including the recently discovered high-temperature materials, an external magnetic field begins to penetrate the material when the field exceeds a certain critical value.
However, in Type II superconductors, including the recently discovered high-temperature compounds, the materials actually retain an internal magnetic field if the external field is greater than a certain value.
