Synthesis and structural properties of hexagonal-LuFeO3 nanoparticles

Hexagonal LuFeO3 nanoparticles were synthesized using sol-gel method. XRD reveals its structure in P63cm space group which has polar symmetry. Microstructure exhibits homogeneous particles with an average grain size of 60 nm. Raman spectra shows 13 active phonon modes corresponding to the P63cm space group. Results are discussed in detail.

Structural and magnetic properties of polycrystalline La2NiMnO6 thin films

Polycrystalline thin films of La2NiMnO6 (LNMO) are deposited successfully on SiO2/Si substrates using pulsed laser deposition technique. Structural characterization using X-ray diffraction confirms the formation of a single phase with P21/n space group. Cross-sectional FE-SEM shows the film thickness ∼195 nm. The deposition temperature and the oxygen pressure played a crucial role determining the crystallization behavior and the magnetic transition temperatures. The ferromagnetic transition temperature is achieved to be ∼277 K by optimizing the deposition conditions.
