E. Lelievreberna et al., FIELD-INDUCED 1ST-ORDER MAGNETIC TRANSITION AND ASSOCIATED VOLUME EFFECT IN TBMN2, Journal of magnetism and magnetic materials, 137(1-2), 1994, pp. 120000006-120000010
Magnetostriction experiments have been performed on a TbMn2 polycrysta
lline sample. A large volume shrinkage is shown when applying a magnet
ic field in the ordered low temperature magnetic phase. It confirms th
e occurrence of a field induced first order transition from a Mn antif
erromagnetism to a magnetic structure where magnetic and non-magnetic
Mn are coexisting.
