【摘要】 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。更多还原

【Abstract】 The lattice of YFe₁₀V₂ is expanded by hydrogen. Hydrogen increases both the magnetization andCurie temperature,but decreases Fe-Fe interaction coefficient.Hydrogen does not change the uniaxialanisotropy of YFe₁₀V₂ but decreases it obviously.Mossbauer spectra have showed that the hperfinefield and isomer shift of each Fe site are increased by hydrogen,and the increment becomes smaller atlow temperature,The Mossbauer spectrum results, combining with the magnetization measurement.have proved the existence of the moment of Y and V atom which are antiferromagnetically coupledwith Fe moment更多还原
