New Condensed Matter Findings from Indian Institute of Technology Reported (Raman scattering spectra, magnetic and ferroelectric properties of SiFeO3-CoFe2O4 nanocomposite thin films structure)

By a News Reporter-Staff News Editor at Physics Week -- Current study results on Condensed Matter have been published. According to news reporting from Delhi, India, by VerticalNews journalists, research stated, "Multiferroic (1-x)BiFeO3(BFO)-xCoFe(2)O(4)(CFO) (x=0 and 0.1) nanocomposite thin films were deposited on ITO coated glass using sol-gel spin coating technique. X-ray diffraction and transmission electron microscopy examinations confirm the coexistence of both perovskite BFO and spinet CFO phases."

The news correspondents obtained a quote from the research from the Indian Institute of Technology, "The effect of addition of CFO in BFO matrix has been studied on Raman spectra, magnetic and ferroelectric properties. BM/CFO nanocomposite showed good magnetic behavior (M-s similar to 40.3 emu/cm(3), M-r similar to 12.9 emu/cm(3), H-c similar to 90 Oe) with no change in ferroelectric properties. The strain analysis carried out by Raman spectroscopy reveals that both BFO and CFO bands are found to be strained in BFO/CFO composite nanostructure."

According to the news reporters, the research concluded: "The strain of the bands is discussed on the basis of lattice mismatch (interfacial stress) between CFO (a=0.839 nm) and BFO (a=0.396 nm) phases."
