We have measured the magnetoresistance of two stadium-shaped cavities for which chaotic scattering is expected. The resistance fluctuates on a field scale which depends on the cavity size. We fit the power spectra of the fluctuations to semiclassical chaotic scattering theory. In the smaller stadium we observed a ballistic weak localization effect, but not under all conditions.
