| Abstract: | Measurements of the magnetostrictive coefficients λγ,2, λα,21 and λα,22 have been made for a range of alloy compositions and temperatures. The variation of λγ,2 with temperature and composition is consistent with the proposition that the strains are due to single-ion type interactions.Although the accuracy of measurement of the λα,21 and λα,22 coefficients is lower and the range of composition over which measurement could be made more restricted the results from these measurements also support a single-ion model. |
