摘要: Abstract The effect of absorbed hydrogen on the structural and magnetic properties DyFe 11 Ti has been investigated. compound was hydrogenated to composition TiH x , where ranges from 0 1.5. absorption pressure-composition isotherms hydrides indicate solid solution behavior. Hydrogen does not change tetragonal structure host but is accompanied by an expansion in unit cell volume. Magnetic characteristics material its (measured situ a atmosphere) were investigated over temperature range 77–700 K at applied fields up 12 kOe. Upon hydrogenation ordering T c as well spin-reorientation temperatures sr are observed increase. Moreover, incorporation leads which anisotropy rare-earth sublattice dominates that iron sublattice.
