| Abstract: | Exchange (or multiplet) splitting, ΔEs of the 3s core-level of Mn in RMn2Si2 (R = La to Nd, Sm and Gd) has been observed using XPS technique. The measured value of ΔEs is used to determine the magnetic moment on Mn ion in RMn2Si2. ΔEs has also been measured for the 4s and 5s levels of R in RMn2Si2 and it is found that the value of ΔEs increases with increase in the number of unpaired spins (La to Gd). |
