Copper-doped lanthanum manganite LaCeSrMn Cu O influence on structural, magnetic and magnetocaloric effects.

Bulk nanocrystalline samples of LaCeSrMn Cu O (0 ≤ ≤ 0.15) manganites are prepared by the sol-gel based Pechini method. The effect of the substitution for Mn with Cu upon the structural and magnetic properties has been investigated by means of X-ray diffraction (XRD), Raman spectroscopy and dc magnetization measurements.
