The magnetostriction of (Fe<inf>1-x</inf> Co<inf>x</inf>) Tb (0¿×¿1.0) compounds and amorphous Fe<inf>3</inf>Tb alloys were measured at room temperature and at 77K. The value of ¿<inf>¿</inf>-¿<inf>¿</inf> at 77K and 20 kOe of (Fe<inf>1-x</inf>Co<inf>x</inf>)<inf>3</inf>Tb compounds increases drastically from 1500×10<sup>¿6</sup> to 3000×10<sup>¿6</sup> as x is increased from 0 to 1.0. The value of ¿<inf>¿</inf>-¿<inf>¿</inf> for amorphous Fe<inf>3</inf>Tb is about 30 to 40% smaller than the… CONTINUE READING
