On the other hand, the forced convection should be kept high enough to prevent floating particles attaching to the growing crystal. Therefore, in order to grow a larger single crystal, it was necessary to control the crystal rotation rate according to the change of the crystal diameter with ...
X-ray experiments on single crystals 2–3 have reported that the oxygen vacancies are distributed in an ordered way in the plane containing Y atoms (z = 1/2) and statistically in the plane at z = 0. High-resolution neutron-powder diffraction 4,5 showed, on the other hand, a reduction...
On the other hand, the above-discussed striking analogy with NbSe2 is suggestive of an opposite explanation: CDW fluctuations become frozen by disorder on approaching a putative CDW transition at TCDWooTonset. The transition observed at TchargeE60 K could then naturally correspond to TCDW but it...
On the other hand, for the same thickness of YBCO layer, the irreversibility lines did not change (except for a slight change in the superconducting transition temperature Tc) for YBCO/PBCO multilayered films having PBCO layers that were from three to eight unit cells t 展开 ...
On the other hand, Zn-doped YBCO or PBCO SNS junctions shows flux-flow type I–V characteristics. The improvement of IcRn product, 255 μV, of the Fe-doped YBCO SNS junctions comes from high value of Rn=0.88 Ω to compensate low value of Ic=290 μA by the improvement of ...
The current suppression is caused on the one hand by the dense packing of pinhole-like defects. On the other hand, we observe a substantial current anisotropy being related to the surface morphology of the buffer layers and the direction of the IBAD-beam. ...
On the other hand, lattice constant of c-axis considerably decreases against oxygen pressure and obtained a minimum value at 74 kPa. This corresponds to the maximum of Tc and M constant maximum. It seems that the optimum amount of oxygen was obtained at this oxygen pressure. The average ...
Front controls are up and down toggle switches for Source (MM/MC) and Power (on/off). There is also a master power switch under the unit on the left-hand side. The heart of the PH-1 is the op-amp based moving-magnet section, which works alongside a moving-coil transformer. As well...
Most techniques used to probe the magnetization of superconductors represent averages over the entire volume of the sample. This precludes the study of defects, and also raises the question of whether the observed behaviour is intrinsic or is dominated by defects. On the other hand, spatially ...
The films had an oxygen deficit of 6.6–6.8%. Initially, T c was 74 K. After the treatments by the strong pulses of magnetic fields, T c had increased to 80 K. On the other hand, in YBa2Cu3O x (5% Ag), the processing by strong pulsed magnetic 展开 ...
