SQUID magnetometer using sensitivity correction signal for non-magnetic metal contaminants detection
Publikováno v:
Physica C: Superconductivity and its Applications. 530:109-112
Measurement methods with SQUID can accurately detect small magnetic metal contaminants based on their magnetic remanence. But, a high-frequency excitation is necessary to detect nonmagnetic metals, on the base of contrasts in electric conductivity. I

When performing high-sensitivity magnetic measurements via a high-sensitivity magnetic sensor such as a SQUID (Superconducting QUantum Interference Device) magnetometer, it is necessary to shield from environmental magnetic noise by employing a magne

In a conventional transformer, secondary voltage and power transfer efficiency decrease when the magnetic flux leaks from the magnetic circuit of the transformer and the leakage reactance increases. Magnetic shielding of the magnetic circuit of the t

The authors systematically investigated the effects of discharge gas pressure on in situ YBaCuO thin-film formation by RF magnetron sputtering and ensured the reliability of the epitaxial YBaCuO films by pressure control. The film (100-nm thick and n

The hole-carrier transport in the epitaxial (001) Y{sub 1}Ba{sub 2}Cu{sub 3}O{sub y} thin films has been closely investigated under the application of pulsed high electric field. In every current-electric field curve of the normal conduction, strong

The feasibility of the selective (001)Y I Baz Cu3 0 epitaxy have been closely examined. We have obtained the selective growth of epilaxial Y 1 Baa CUJ 0 and heteroepitaxial (100)MgO/(001)- Y1 Baz Cu3 0 layers through the Si0 window. The MOS-capacitor

Homoepitaxy of the diamond thin films has been carried out by employing the ECR microwave plasma CVD apparatus with a CO/H2 gaseous source. From RHEED observation, it appeared that the surface morphology of (100) oriented film was much better than th

The significant current saturation against the 20‐ns‐wide pulsed electric field above the threshold value E th (∼2 kV/cm) was observed in the semiconducting phase YBa2Cu3O y epitaxialfilms at low temperatures. Although E th increased up to 3–
