Electrodynamics of correlated electron materials (2011, background): “Discovered in 2001, this material becomes superconducting below Tc= 39 K which was, at the time of discovery, an unexpected result for a simple intermetallic compound (Nagamatsu et al., 2001).”
Experimental realization of two-dimensional boron sheets. (2015, background): “In fact, compound MgB2, which is composed of alternating boron layers and Mg layers, exhibits high Tc superconductivity at ambient pressure [21].”
Novel BiS2-based layered superconductor Bi4O4S3 (2012, background): “Layered magnesium diboride MgB2 exhibits a comparably high Tc of 39K although it is a simple binary compound.(14) Layered nitride HfNCl and ZrNCl are band insulators.”
Very High Field Two-Band Superconductivity in LaFeAsO_0.89F_0.11 (2008, background): “To analyze the experimental data, we use the theory of two-gap s-wave pairing, which has been recently applied to describe the behavior of MgB2 (see, e.g., a review Ref.”
Angle-resolved photoemission studies of quantum materials (2020, neutral): “MgB2 and graphite intercalation compounds MgB2 with Tc = 39 K holds the Tc record for any binary compound under ambient pressure (Nagamatsu et al., 2001).”
