What is Investigation of magneto-electric properties of La0.85Nd0.15Fe0.9Ti0.1O3 about?
Solid state reaction route was employed to synthesize nanoparticles of undoped LaFeO 3 (LFO) and Nd 3+ -Ti 4+ codoped LFO (La 0.85 Nd 0.15 Fe 0.9 Ti 0.1 O 3 , LNFTO) therein was considered to modulate its magneto-dielectric properties. The prepared samples were annealed at 1400 °C for 4 h to get the desired crystallographic phase. From the recorded X-ray diffractograms (XRD) it was confirmed that both dopants, Nd 3+ and Ti 4+ successfully entered in LFO lattice with some deviations from ideal perovskite lattice where the FeO 6 octahedron is distorted. The XRD data were also used for extracting cell parameters using Rietveld analysis. Raman spectroscopic data of LFO and LNFTO were recorded at room temperature (RT) to identify the presence of impurities, if any. Magnetization (M) vs applied field (H) of LNFTO recorded at 300, 5 and 2 K show the presence of magnetic ordering with fruitful modulations in shape of curve and value of magnetization in co-doped sample compared to those of LFO. Analysis of M vs temperature (T) curve indicates that co-doped sample of LNFTO is in mixed phase of ferromagnetism and antiferromagnetism. Frequency-dependent dielectric constant (ε ′ ), dielectric l
