Abstract

Thin-film (Formula presented) has been studied with in-plane magnetic fields (Formula presented) to 850 T, with good signal-to-noise to 300 T, using a GHz-transmission-line technique for electrical transport measurements in explosive-driven microsecond pulsed magnetic fields. At an ambient temperature of 1.6 K with (Formula presented) axis we find an onset of dissipation at 150 T, the highest field reported, with a saturation of resistivity at 240 T. Comparison with the Pauli limit (Formula presented) T expected for this material suggests that the critical field is limited by spin paramagnetism.
