摘要：
The unit cell volume dependence of the Curie temperature of Gd2Fe17 is studied by means of high-pressure Mossbauer spectroscopy. From the pressure dependence of the average isomer shift of Ge2Fe17 at room temperature, the contribution of the pure magnetovolume effect to the change of the average isomer shift is derived. By combining the Mossbauer measurements of Gd2Fe17Cx with different C concentrations at room temperature, the change of IS in Gd2Fe17Cx is dominated by the magnetovolume effect. The contribution of the chemical bonding effect is about 24% of that of the magnetovolume effect, but with negative sign.
