According to experimental results in which the dehydrogenating properties of MgH2 systems were improved by addition of NiF2 as catalyst, the energy to remove H atoms, the geometry and electronic structure of MgH2 systems were calculated by using Dmol 4.1 program based on the density functional theory, and the mechanism of improved properties on Ni doped MgH2 systems were also analyzed.

The results show that although both Ni substitution and Mg vacancies are effective in desorbing hydrogen at lower temperatures, the substitution of Ni at the Mg site is energetically more favorable than the formation of Mg vacancies. The Ni atoms of NiF2 can replace some Mg atoms of MgH2 systems, the reaction of NiF2+3MgH2=MgF2+Mg2NiH4 during mill process is accelerated, thus, MgH2 with the higher stability can be changed into Mg2NiH4. Because of a ternary hydride Mg2NiH4 with lower stability forming, the dehydrogenating properties on Ni doped MgH2 systems are improved.

结果表明：Ni替代Mg和创造Mg空位对MgH2体系解氢而言，均发挥有益作用，而形成Mg空位所需能量(6.51 eV)高于Ni替代Mg所需能量(2.12 eV)，表明低温下Ni替代Mg对MgH2体系解氢而言更有利，至此NiF2中的Ni替代MgH2中的Mg，有利于加速化学反应NiF2+3MgH2=MgF2+Mg2NiH4向右进行，使结构稳定的MgH2发生转变，生成结构不稳定的Mg2NiH4，这样体系解氢过程不是通过MgH2，而是转变为通过Mg2NiH4进行，因此，Ni掺杂提高了MgH2体系的解氢性能。

Increased spin disorder and a decrease of with increasing Fe content are evident. It depopulates the hopping electrons and weakens the double exchange. From resistivity and magnetization data, it is expected that the addition of Fe can introduce grain boundaries and form antiferromagnetic clusters.

电阻率的峰值随着Fe的增加而增大，并且峰值对应的温度TIM向低温移动，随着外加磁场的增大电阻下降，产生MR效应，这是因为随着掺杂的增加，自旋无序增加，外场的增加抑制了自旋的扰动，在顺磁温区内，电子自旋形成了随机的磁结构，产生电子局域，破坏了极化子形成的环境，因此输运机制由绝热极化子输运转变为变程跳跃机制。
