Predictions of a magnetic field-induced superconducting state in semiconductors, at fields well above H/sub c/ values for normal and high-T/sub c/ superconductors, have motivated experiments in pulsed magnetic fields up to 700 T. We present results on low density 3D electron systems confined in high-quality Al/sub x/Ga/sub 1-x/As/GaAs parabolic quantum well structures, a prime candidate for this behaviour. The data show immunity to electromagnetic noise generated by the pulse for fields up to 500 T, however, eddy-current heating precluded the observation of field-induced superconductivity. |
