Recent innovations in sample lithography and measurement techniques have made possible electrical transport measurements on both high-Tc superconductor and semiconductor samples in the harsh environment of implosively generated magnetic fields B up to 800 T, with reliable data obtained up to 300 T. Thin films of the cuprate superconductor YBa2Cu3O7-δ have been studied with B directed parallel to the CuO planes (J∥B⊥c-axis). At an ambient temperature of 1.6 K and a probe frequency of 0.9 GHz we find an onset of dissipation at Bon = (150 ± 20) T, the highest field yet reported. In addition, the measured upper critical field Bc2 = (240 ± 30) T is significantly above the paramagnetic limit for this material. Measurements on AlxGa1-xAs/GaAs parabolic quantum well structures, designed to probe the existence of a magnetically induced triplet superconducting phase, and on HgSe : Fe samples are also discussed.
