M. Morales et al., Magnetic characteristics of Er(Mn12-xFex) compounds (x=7, 9) determined byX-ray magnetic circular dichroism, J ALLOY COM, 317, 2001, pp. 470-474
The RMn12-xFex series of compounds of ThMn12 structure type exhibit particu
larly complicated and composition sensitive magnetic properties. Previous n
eutron diffraction and magnetisation experiments have permitted to relate t
he main features to the strength of the local magnetic moments (3d polarisa
tion) and the nature exchange forces between the Mn, Fe and R sublattices.
X-ray magnetic circular dichroism analyses have been undertaken on iron ric
h compounds with R=Er. They allow to better understand the thermal and fiel
d behaviour of the local magnetic moments as well as the nature of the magn
etic couplings between the 3d metals. (C) 2001 Elsevier Science B.V. All ri
