A robotic three-dimensional (3D) scanning superconducting quantum interference device (SQUID) imaging system was developed for practical nondestructive evaluation (NDE) applications. The major feature of this SQUID–NDE system is that the SQUID sens

Superconducting properties were measured for polycrystalline nearly single-phase samples of Pr1−xCexLaCuO4+δ (PLCCO) (0⩽x⩽0.2). Thermoelectric power (S) was found to be negative for all the samples in the temperature range between 50 and 310 K

Crystal growth of YCuO 2 delafossite was studied by a traveling solvent floating zone method. The crystals were grown at the traveling speed of less than 0.2 mm/h in flowing N 2 +18∼21%O 2 gas mixture to prevent the formation of Y 2 Cu 2 O 5 phase

Structural and physical properties of Sr 2-x La x NbO 4-δ (0≤x < 0.2) with ordered-perovskite structure were investigated. Powder X-ray diffraction analysis showed that the samples with 0≤ x≤ 0.1 were of nearly single phase. For all the sample
