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.
