Abstract

In order to research the high magnetostriction effect of some rare-earth transition metal intermetallic compounds such as the RFe2 or RCo2, systems, we have investigated microscopically the physical properties of Dy(Fe1−xCox)2 by Mössbauer spectroscopy. Hyperfine field(Bbf), quadrupole splitting(Q.S.) and isomer shift(I.S.) in the Dy(Fe1−xCox)2 system have been measured at room temperature and 78 K. The easy axis of magnetization lies along the [100] axis. Especially we have found the close correlation between Q.S. and magnetostriction, that is the Q.S. for Dy(Fe1−xCox)2 increase in the Co rich region where the magnetostriction become large at 78 K.
