Abstract
The compound systems RFe4+xAl8-x with ThMn12 type structure have been studied from the Mössbauer effect and a.c. susceptibility in the range of 0 ≤ x ≤ for R = Gd, Er and Y. In these compound systems, site occupancy of Fe atom is different from each other and this fact causes the differences in magnetic properties.
