Phase-sensitive detection of magnetoresistivity by the four-probe technique in pulsed high magnetic fields

Abstract
The authors demonstrate that for four-probe measurements the application of high-frequency, phase-sensitive modulation in pulsed magnetic fields yields the same sensitivity and signal-to-noise ratio that has so far been the privilege of DC magnetic fields. In this way the combination of phase-sensitive modulation and pulsed magnetic fields opens a new class of experiments in high-field magneto-spectroscopy.
