Conductor losses in superconducting transformers
Cryogenics, 1969Abstract An estimate is made of the losses in superconducting transformer windings. If these are not to be excessive, the transformer has to have a large rating.

Parameters of high-temperature superconducting transformers
Thermal Engineering, 2015Parameters of the high-temperature superconducting (HTSC) transformer with a core-type magnetic circuit and with coaxial and symmetrical interleaved windings made of the first-generation HTSC wire with a localized magnetic field are considered. The parameters of the most widespread core-type transformer with a coaxial HTSC winding are compared with ...

Superconducting screening for squid flux transformers
Cryogenics, 1977When a SQUID (Superconducting Quantum Interference Device) is used as a detector of magnetic flux, it is common practice to couple the flux to be measured into it via a flux transformer. As Fig. 1 shows, there is a need for an effective shield around the interconnexions of the two coils of the flux transformer.

SQUID operation with ferromagnetic core superconducting dc transformers
Cryogenics, 1975Abstract We successfully used ferromagnetic core (Cryoperm 10) superconducting transformers to enhance the transfer of external magnetic flux to a symmetric two-holes rf biased quantum interference device (SQUID). The flux transfer ratio has been enhanced up to a factor of ten in comparison with air core superconducting transformers.

Superconductivity and structural transformation in HfRuAs
Physics Letters A, 1983Abstract HfRuAs exists in two structural modifications. The high-temperature phase (ZrRuSi-type structure) exhibits superconductivity at 4.93-4.37 K, whereas the low-temperature phase (TiFeSi-type superstructure) remains normal at 1 K. The lattice distortion giving rise to the superstructure indicates zig-zag chains of metal atoms are crucial to ...
