Abstract
The superconductivity and the lattice properties of a sintered MgB2 material havebeen investigated under high pressure up to 10 GPa. The transition temperature wasfound to decrease linearly with increasing hydrostatic pressure at a rate of 1.03 KGPa−1, which can be explained with the classical Bardeen–Cooper–Shrieffer theorybased on an electron–phonon coupling mechanism. The crystal lattice exhibits ananisotropic compressibility characterized by a larger compressibility along thec-direction thanthe a/b-directions.The anisotropy is attributed to a weaker inter-plane bonding along thec-axisin comparison with a stronger intra-plane bonding perpendicular to thec-axis.The bulk modulus of the measured material was deduced to be 172 GPa.
