摘要：

Materials that exhibit colossal magnetoresistance (CMR) are currently the focus of an intense research effort, driven by the technological applications that their properties suggest. Using the angular correlation of photons from electron-positron annihilation, we present a first view of the Fermi surface of a material that exhibits CMR, supported by 'virtual crystal' electronic structure calculations. The Fermi surface is shown to be sufficiently cubic in nature that it is likely to support nesting.
