Magnetostriction of the itinerant uniaxial ferromagnet Y{sub 2}Fe{sub 14}B
- Departamento Fisica de Materia Condensada ICMA, Universidad de Zaragoza--CSIC, 50009 Zaragoza (Spain)
Magnetostriction measurements have been performed on a tetragonal Y{sub 2}Fe{sub 14}B single crystal along all the major symmetry directions at temperatures ranging from 10 to 400 K and applied magnetic fields up to 14 T. The standard irreducible magnetostrictive modes for tetragonal symmetry, {epsilon}{sup {alpha},1}({bold c}), {epsilon}{sup {alpha},2}({bold c}), {epsilon}{sup {alpha},1}({bold a}), {epsilon}{sup {alpha},2}({bold a}), {epsilon}{sub 1}{sup {gamma}}({bold a}), and {epsilon}{sup {epsilon}}({bold d}), have been obtained from the measurements. Their thermal and applied magnetic-field dependence are discussed. The isotropic volume striction modes have been observed to be one order of magnitude higher than the anisotropic ones. {copyright} {ital 1997 American Institute of Physics.}
