吸氢使ＹＦｅ＿（１０）Ｖ＿２晶格膨胀，磁化强度和居里温度增加，但使Ｆｅ－Ｆｅ的交换作用系数减小。吸氢不改变铁亚晶格的单易轴磁结构，但使单轴各向异性减弱。氢使各铁晶位的超精细场和同质异能移位都增加。各超晶细参数受氢的影响随温度的降低而减小。磁测量和穆斯堡尔谱的结果表明，在ＹＦｅ＿（１０）Ｖ＿２中，钇和钒原子有一与铁亚晶格反平行耦合的磁矩。
Hydrogen absorption expands the lattice of YFe_ (10) V_2 and increases the magnetization and the Curie temperature, but decreases the exchange coefficient of Fe-Fe. Hydrogen absorption does not change the single-easy-axis magnetic structure of iron sub-lattice, but weakens uniaxial anisotropy. Hydrogen increases the hyperfine field and homogenous energy shifts in each iron site. The influence of the super-fine parameters by hydrogen decreases with decreasing temperature. The results of magnetic measurements and Mossbauer spectroscopy show that in YFe_ (10) V_2, the yttrium and vanadium atoms have an antiparallel-coupled magnetic moment with the iron sub-lattice.
