Abstract

The effect of nonmagnetic substitution in a perovskite ferromagnetic insulator Pr0.8Ca0.2MnO3 was studied in epitaxial Pr0.8Ca0.2Mn1-yScyO 3 thin films grown on SrTiO3 substrates. An increasing Sc substitution level weakened the ferromagnetic order, resulting in a decrease of saturation magnetization and the ferromagnetic transition temperature. Analysis of transport properties and Raman spectra indicates that besides simple spin dilution, weakening of both the double-exchange interaction and orbital order contributes to the reduction of ferromagnetic order.
