Probing into the power applications, the author tracked down that the key factor restraining the high power applications for a type-II superconductor
is the - irreversibility line Hirr(T) that bounce back the very boundary of resistive dissipation of phase diagram in magnetic field vs.
* Field-cooling magnetization (FCM), where a large magnetic field is applied to a bulk superconductor
above its superconducting transition temperature, Tc, which is subsequently cooled to a particular cryogenic operating temperature, Top, then the field is removed;
have electrons that conduct electricity with no resistance to flow.
A typical superconductor
has about one mobile electron for each atom in the material, while in bismuth each electron is shared by 100,000 atoms.
The new record was achieved using two 25mm diameter samples of GdBCO high-temperature superconductor
, fabricated in the form of a large, single grain by an established melt processing method and reinforced with a relatively simple technique.
Meadows a few days before American Superconductor
announced that it expected fourth-quarter and fiscal year-end results to be weaker due to a deteriorating relationship with its primary customer, China-based Sinovel Wind Group Co.
The periodic structure consisting of alternate superconductor
and dielectric layer with graded thicknesses is depicted in Figure 1.
can be manufactured much more efficiently and with less environmental impact by means of the innovative production process developed by technology company Deutsche Nanoschicht GmbH.
High temperature superconductors
have remarkable properties: they conduct electricity with zero resistance, even with simple cooling by liquid nitrogen; they can withstand high magnetic fields and huge current densities - and they continue to be superconducting throughout the plasma pulse in a tokamak.
In a filing to the US Securities and Exchange Commission, American Superconductor
said it "believes that Sinovel illegally obtained and used the company's intellectual property".
Zenergy Power PLC (ZEN.LN), a superconductor
energy technology company, has received a contract from Applied Superconductor
Shen and his team looked at a sample of a cuprate superconductor
and examined electronic behavior at the sample's surface, thermodynamic behavior in the sample's interior, and changes to the sample's dynamic properties over time.
