摘要
本文使用哈密顿矩阵,计算出CsNiCl3的能级和g因子随温度的变化,分析出Ni2+-Cl-键长从5K~300K的热膨胀,得到线性热膨胀为:δR=R(300K)-R(5K)=2×10-2和线性热膨胀系数:α=1RdRdT=2.73×10-5K-1.
The theoretical energy levels and g-factor have been caleulated by using the Hamiltonian matrices. The thermal expansion of the Ni 2+ -Cl - bond for CsNiCl 3 in the temperature range 5K-300K has been calculated. In this way, the linear thermal expansion δR=R(300K)-R(5K)=2×10 -2 and the linear thermal expansion coefficient α=1R d R d T=2.73×10 -5 K -1 for the Ni 2+ -Cl - bond are abtained.
