【 摘 要 】
Results of ab initio electronic structure calculations on the compound MgB2 using the FPLAPW method employing GGA for the exchange-correlation energy are presented. Total energy minimization enables us to estimate the equilibrium volume, ð‘/ð‘Ž ratio and the bulk modulus, all of which are in excellent agreement with experiment. We obtain the mass enhancement parameter by using our calculated ð·(ð¸F) and the experimental speciï¬c heat data. The ð‘‡c is found to be 24.7 K.【 授权许可】
