Room temperature Mössbauer spectra of (BiFeO3)1−x (PbTiO3)x (x = 0, 0.1, 0.2, 0.3) nano multiferroic systems prepared by solution combustion technique reveal the long range ferromagnetic ordering, supported by M-H loop measurements. Magnetic hyperfine interaction field and isomer shift for these nanocrystallite indicate the presence of Fe3 +  ion only, likewise confirmed by from X-ray photoelectron spectroscopy study, which is essential for enhancement of multiferroic properties. A small residual magnetic moment is observed for these nanoparticles, which may be attributed to size confinement at nanoscale and to spin canting. These nanomaterials are of great importance in basic as well as applied research.
