Synthesis and Characterization of the Possible MgB2-like Superconductor MgBC

ORAL

Abstract

Currently, MgB2 is the conventional superconductor with the highest critical temperature (Tc) of ~39 K. Recent computational predictions suggest that a related material, MgBC, is thermodynamically stable under high-pressure conditions and possesses a Tc in a similar range. In this work, we explore the experimental synthesis of MgBC under pressure in a laser-heated diamond anvil cell (DAC) and investigate the structure and bonding using X-ray diffraction and Raman spectroscopy. Potential superconducting properties were investigated using in situ electrical transport measurements.
