Raman spectra, photoluminescence, magnetism and magnetoelectric coupling in pure and Fe doped BaTiO3 nanostructures

An Eco-Friendly Method of BaTiO3 Nanoparticle Synthesis Using Coconut Water

“…A predominant rod-like morphology can be observed in both regions with structures that are 200-400 nm in length. The nonequiaxial growth of BaTiO 3 particles with a tetragonal crystalline structure has also been recently reported using BaTiO 3 powders produced by a hydrothermal method [33], sonochemical synthesis followed by thermal treatment [34], and a solvothermal method using ethylene glycol as a solvent [35]. Rod-shaped particles are particularly advantageous in catalysis applications.…”

Multiferroic Ni0.6Zn0.4Fe2O4-BaTiO3 nanostructures: Magnetoelectric coupling, dielectric, and fluorescence

“…It is believed that the present case involves under dispersed conditions; the steric hindrance may have led to effective collisions in only one crystallographic direction due to different ionic radii of all metal ions resulting into formation of nanowires like structure. 7 Figures 4, 5(a), and 5(b) show the coexistence of ferroelectricity and ferromagnetism of CNZF/BT and HNZF/BT nanostructure, respectively, by measuring polarization versus electric field (P-E) and magnetization versus magnetizing field (M-H) hysteresis curves at room temperature. The P-E hysteresis loops measured at room temperature on poled specimen of CNZF/BT composite with 50 Hz frequency of polarization [ Fig.…”

“…These values of a E are given in Table I and show improvement than the reported work of BT based composites. 7,12,13,[24][25][26][27][28][29][30][31][32] Generally, the value of a E linearly increases to a maximum value and then deceases linearly to zero with varying H dc of applied magnetic field. But, in the present case of NZF/BT, the a E is nonlinearly varying and also observe stability at certain value of applied H dc magnetic field depends on two factors: first, the two-phase nanostructural composite coupled by interfacial strain where ME behavior is strongly dependent on their nanograins and the coupling interaction across the piezoelectric/magnetostrictive interface.…”

“…6,7 Alternatively and with greater design flexibility, MF composites have been introduced, where a magnetostrictive phase is mechanically coupled to a piezoelectric phase, originating from the elastic interaction among the subsystems via stress mediation. 8 A large magnetoelectric output voltage has been observed in Pb based MF composites.…”

“…3,11,13 The second process is hydrothermal, which is surfactant free, and the size and shape of nanostructure depends on the adjustment of pH value, hydrolysis time, and temperature. 7,16 In the present paper, we have prepared MF composite of Ni 0. 6 O 4 Ti), polyethylene glycol (PEG), and urea taken in desired stoichiometric ratios.…”
