摘要:

研究了多晶Ce(Fe 0.975Ga 0.025)2的磁性和磁结构特性随温度和磁场的变化。在Ce(Fe 0.975Ga 0.025)2中,从反铁磁态(AFM)到铁磁态(FM)的磁性转变伴随着从菱面体结构到立方结构的结构转变。在温度和场驱动的从AFM相到FM相的转变过程中,存在相共存。

英文摘要:

The magnetic and magnetostructural properties of the polycrystalline Ce(Fe0.975Ga0.025)2 have been investigated as a function of temperature and magnetic field. In Ce(Fe0.975Ga0.025)2 the magnetic transition from antiferromagnetic (AFM) to ferromagnetic state (FM) is accompanied by a structural transformation from rhombohedral to cubic structure. Phase coexistence is present during both the temperature and field driven transformations from the AFM to FM phase.
