Description

Elastic moduli and magnetostriction data are reported for polycrystalline Tb6Fe1-xCoxBi2 (0 ≤ x ≤ 0.375). The elastic moduli c11 and c44 have been measured as a function of temperature (5-300 K) and magnetic field (0-5 T), and reflect the ferromagnetic transition observed in these materials around 250 K. A remarkable elastic softening, which is partially suppressed upon application of a magnetic field, is observed at low temperatures and is believed to be linked to a structural transition that takes place in the Co-doped samples. The soft elastic moduli lead to large magnetostriction below 50 K, reaching a value of 700 ppm at 20 kOe for Tb6Fe0.75Co0.25Bi2.
