Effect of magnetic field on the transition temperature of high-Tc superconductors in sound velocity measurementsWe observed discontinuities in sound velocity VS(T, H) versus T curves near Tc, for {YBa2Cu3O7} and (La1x,Srx)2CuO4 (x = 0.075). By applying magnetic field, however, the ...

Changes in the display of a mass balance caused by the effect of the earth's magnetic field were measured at the Korea Research Institute of Standards and Science (KRISS) using the Bureau International des Poids et Mesures (BIPM) susceptometer operating in a Helmholtz coil system. The experimen...
Quantum phase transition in the magnetic-field-induced normal state of optimum-doped high-Tc cuprate superconductors at low temperatures. A 60 T magnetic field suppresses the superconducting transition temperature T_{c} in La_{2-p}Sr_{p}CuO_{4} to reveal a Hall number anomaly, which develops...
of magnetic NiO nanoparticles in YBCO resulted in improved critical current density and flux pinning force in the measured range of temperature and magnetic fields. The observed high pinning at a lower field is attributed to the magnetic interaction of vortices with the NiO nanoparticles. At 60 K...
Magnetic effectsMean field theoryWe explore the occurrence of a magnetic-field-induced finite-size effect on the specific heat and correlation lengths of anisotropic type-II superconductors near the zero-field transition temperatureTc. Since near the zero-field transition thermal fluctuations are expected...
We have recently reported1 that the integrated voltages S ∝∫ V(t) dt observed across an open single-layer superconducting coil, when a magnetic flux Δ∅ trapped in the body of the coil winding is expelled, are not uniquely described by the...
High-quality YBa 2Cu 3O 7 films were deposited on MgO(1 0 0) substrates by a metalorganic chemical vapor deposition process in a high magnetic field. The orienting effect was effectively produced by the application of magnetic field. The J c of the films deposited under a field of 8 T ...
