Recently, it was found that MgB[sub 2] is a superconductor with a transition temperature of 39 K. Electronic structure calculations suggest that an incompletely filled σ band in the covalently bonded B layers is critical to the superconductivity. In this work, electron energy-loss spectroscopy was used to verify the electronic structure of MgB[sub 2] and qualitative agreement with calculations in the literature was observed. © 2001 American Institute of Physics.
