Magnetization in high-temperature superconducting strips during transverse magnetic field application

Mostrar todas las versiones(2)

We have investigated both experimentally and numerically the magnetization, M(t), in high-temperature superconducting strips during the application of a transverse magnetic field, Ha(t). Experimental results in GBCO strips were obtained with a short time non-conventional technique for Ha(t) ∼ (1 - e...

Sumario:We have investigated both experimentally and numerically the magnetization, M(t), in high-temperature superconducting strips during the application of a transverse magnetic field, Ha(t). Experimental results in GBCO strips were obtained with a short time non-conventional technique for Ha(t) ∼ (1 - exp(t/τ)), with τ ∼ 1 μs. Calculations take into account the effect of flux creep and/or ohmic overcritical damping and satisfactorily describe the experimental results. © 2000 Elsevier Science B.V. All rights reserved.
