Using Pulse-Echo Overlap Method, the velocities of longitudinal and shear waves of Ceramic MgCNi3 superconductor were measured up to hydrostatic pressure of 0.5 GPa. The bulk modulus B, shear modulus G, Debye temperature and specific heat under pressure were calculated. The values of Debye temperature ΘD and specific heat cV under ambient condition are 454.82 K and 111.30 J/(mol·K), respectively. The B-p curve was fitted linearly to obtain , the first order derivative of bulk modulus at zero pressure. The Murnaghan equation of state was established.

在0.1 MPa到0.5 GPa压力范围内,采用脉冲回波重合法(Pulse-Echo Overlap Method)测量了MgCNi3超导体的横波及纵波声速,计算了体弹模量B、剪切模量G等弹性参数以及德拜温度、比热等热力学参数随压力的变化。常压下的ΘD与cV的值分别为454.82 K和111.30 J/(mol·K)。对B-p曲线作线性拟合,得到体弹模量B0在零压附近的导数,由此建立了MgCNi3的状态方程。

在0.1 MPa到0.5 GPa压力范围内,采用脉冲回波重合法(Pulse-Echo Overlap Method)测量了MgCNi3超导体的横波及纵波声速,计算了体弹模量B、剪切模量G等弹性参数以及德拜温度、比热等热力学参数随压力的变化。常压下的ΘD与cV的值分别为454.82 K和111.30 J/(mol·K)。对B-p曲线作线性拟合,得到体弹模量B0在零压附近的导数,由此建立了MgCNi3的状态方程。

MgCNi3  /  超导体  /  弹性模量

Using Pulse-Echo Overlap Method, the velocities of longitudinal and shear waves of Ceramic MgCNi3 superconductor were measured up to hydrostatic pressure of 0.5 GPa. The bulk modulus B, shear modulus G, Debye temperature and specific heat under pressure were calculated. The values of Debye temperature ΘD and specific heat cV under ambient condition are 454.82 K and 111.30 J/(mol·K), respectively. The B-p curve was fitted linearly to obtain , the first order derivative of bulk modulus at zero pressure. The Murnaghan equation of state was established.
