Abstract

The crystal structure and magnetic properties of ( Ru 1-x Sn x) Sr 2 EuCeCu 2 O z and Ru ( Sr 2-x La x) EuCeCu 2 O z(0≤ x ≤0.1) samples have been investigated to shed light on the doping-induced changes in the magnetic properties of Ru -1222 system. We show that La substitution for Sr leads to an increase in the temperature where the ferromagnetic component is observed and a moderate suppression of the ferromagnetic component whereas Sn substitution for Ru results in a significant decrease of the volume fraction of the ferromagnetic phase as well as a decrease in the magnetic ordering temperature. The experimental results are discussed in connection with the structural data studied by Rietveld refinement of the x-ray diffraction data.
