Ky. Mulyukov et al., GIANT MAGNETOSTRICTION BEHAVIOR OF SUBMICROCRYSTALLINE TERBIUM, Physica status solidi. a, Applied research, 161(2), 1997, pp. 493-498
The giant magnetostriction of terbium is investigated in its different
structural states (from submicrocrystalline to a coarse grained struc
ture). The value of magnetostriction in submicrocrystalline state is l
ess than that of coarse grained state by factor of 2.7 in the same mag
netic field. The magnetostriction of all structural states follows hys
teresis loops during changing the magnetic field magnitude with an enh
anced value of coercivity in the submicrocrystalline state and without
coercivity in the coarse grained state.
