- W4285809904 abstract "Multiferroic nanoparticles of single-phase bismuth ferrite (BiFeO 3 or BFO) by choosing transition metal ions of chromium (Cr)/cobalt (Co) in A-sites and manganese (Mn) in B-sites were synthesized by using sol-gel autocombustion method. X-ray diffraction (XRD) data reveal the existence of rhombohedrally distorted perovskite structure for all the samples. High resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDAX) studies were carried out to estimate the particle size, morphology along with the chemical purity of the samples. Dielectric studies as a function of frequency and temperature resemble typical space charge polarization with almost negligible dielectric losses in the doped samples. Magnetic measurements using vibrating sample magnetometer reveals the considerable enhancement in the magnetic order in Co/Cr and Mn co-doped samples. The obtained structural, microstructural, dielectric and magnetic results were well recommended that the influence of co-doping in BFO will certainly modify its spin cycloid structure and hence enhanced properties in these doped samples. Thus, these co-doped samples were suggested to be well suitable for the multifunctional based devices such as spintronic, multifunctional memories, and for sensors. XRD patterns of Bi (1- x ) Tr x Fe (1- y ) Mn y O 3 (where x & y = 0, 0.05 and Tr = Cr/Co) multiferroic samples.Room temperature M − H loops of Bi (1- x ) Tr x Fe (1- y ) Mn y O 3 (where x & y = 0, 0.05 and Tr = Cr, Co). • Preparation of Bi (1-x) Tr x Fe (1-y) Mn y O 3 (where x & y = 0, 0.05 and Tr = Cr/Co) multiferroic nanomaterials were synthesized by sol-gel auto combustion method. • X-ray diffraction (XRD) data reveal the existence of rhombohedrally distorted perovskite structure for all the samples. • High resolution transmission electron microscopy (HRTEM) and energy dispersive X-ray spectroscopy (EDAX) studies were carried out to estimate the particle size along with the chemical purity of the samples. • All the samples resemble typical space charge polarization with almost negligible dielectric losses. • A significant improvement in the saturation magnetization (Ms = 5.12 emu/g) along with highest coercivities (Hc = 1515.2556 Oe) were observed for the Co & Mn co-doped BFO." @default.
