摘要

In this work, The magnetoelastic properties of polycrystalline samples of Tb _3 (Fe _(28-x)Co _x) V _(1.0) (x=0, 3, 6) intermetallic compounds are investigated by means of linear thermal expansion and magnetostriction measurements in the temperature range of 77-515 K under applied magnetic fields up to 1.5 T. The linear thermal expansion increases with the Co content. The well-defined anomalies observed in the linear thermal expansion coefficients for Tb _3 (Fe _(28-x)Co _x) V _(1.0) (x=0, 3, 6) compounds are associated with the magnetic ordering temperature for x=0 and spin reorientation temperatures for x=3, 6. Below transition temperatures, the value of the longitudinal magnetostriction (λ _(Pa)) at 1.6 T increases with Co content.
