Abstract
The thermal expansion, magnetic properties and magnetoelastic effects in amorphous Ce-Fe alloys have been investigated. These alloys exhibit a marked thermal expansion anomaly associated with a significantly la rge spontaneous volume magnetostriction. A large elastic anomaly has b een confirmed even above the Curie temperature. The compressibility ca lculated from the elastic data obtained by Brillouin scattering is abo ut three times that of crystalline b.c.c. Fe. These large magnetoelast ic effects give rise to remarkable pressure effects on the Curie tempe rature, magnetization and spin-wave stiffness constant.
