Improved optical, dielectric, impedance, and magnetic properties of (BiFeO3)0.6(CaTiO3)0.4 for multifunctional utilities

Recent Advances toward Enhanced Photocatalytic Proprieties of BiFeO3-Based Materials

“…The structural deformation from the pure BFO’s rhombohedral structure to an orthorhombic phase was indicated through Rietveld refinement. At RT/10 2 Hz, the dielectric constant was improved with a high value of 1050 [ 108 ].…”

Gd3+-substituted BiFeO3 perovskite nanoparticles: facile synthesis, characterization, and applications in heterogeneous catalysis

“…Multiferroic nanomaterials exhibit structural, optical, electric, and magnetic characteristics that result in dielectric, semiconducting, ferroelectricity, piezoelectric, antiferro/ferromagnetism, and ferroelasticity in the same phase at room temperature, while requiring empty and partly filled transition or rare-earth metal d-orbitals. [1][2][3][4][5][6] They have extensive commercial applications in magnetic/ferroelectric data storage, ecologically friendly devices, low power consumption, photosensitizers, electromagnets, spintronics, and sensor devices. [7][8][9] The chemical formula for the perovskite, which is derived from calcium titanate (CaTiO 3 ), is ABO 3 -type.…”

“…Due to the unpaired electrons in the d shell of Fe 3+ ions and exchange or Dzyaloshinskii-Moriya (D-M) interactions via O 2− ions, the magnetic structure of BFO is a G-type antiferromagnetic, exhibiting extremely weak ferromagnetic activity. 4,6,8,[15][16][17] Bi 3+ ion doping/substitution by rareearth elements such as La 3+ , Tb 3+ , Nd 3+ and Gd 3+ ions led to the destruction of the spin cycloid due to a reduction in oxygen vacancies, as well as an increase in remanent polarisation, spontaneous magnetization, high switchable current, large absorption coefficient, photovoltaic effect, magnetoelectric effect, and physical properties. [17][18][19][20][21][22][23] BFO perovskite materials have exceptional thermal and chemical stability, chemical resistance, and catalytic activity.…”
