“…By contrast, high-spin Fe 3+ possesses 2 unpaired electrons in its e g orbitals. The parent compound, B6TFO has been reported 59,87,88 to be antiferromagnetic with a magnetic transition to weak ferromagnetism below 65K. The mechanism involving ligand orbitals to facilitate coupling between metal electrons is referred to as super-exchange.…”

Single-phase multiferroic materials are of considerable interest for future memory and sensing applications. Thin films of Aurivillius phase Bi7Ti3Fe3O21 and Bi6Ti2.8Fe1.52Mn0.68O18 (possessing six and five perovskite units per half-cell, respectively) have been prepared by chemical solution deposition on c-plane sapphire. Superconducting quantum interference device magnetometry reveal Bi7Ti3Fe3O21 to be antiferromagnetic (TN = 190 K) and weakly ferromagnetic below 35 K, however, Bi6Ti2.8Fe1.52Mn0.68O18 gives a distinct room-temperature in-plane ferromagnetic signature (Ms = 0.74 emu/g, μ0Hc =7 mT). Microstructural analysis, coupled with the use of a statistical analysis of the data, allows us to conclude that ferromagnetism does not originate from second phase inclusions, with a confidence level of 99.5%. Piezoresponse force microscopy (PFM) demonstrates room-temperature ferroelectricity in both films, whereas PFM observations on Bi6Ti2.8Fe1.52Mn0.68O18 show Aurivillius grains undergo ferroelectric domain polarization switching induced by an applied magnetic field. Here, we show for the first time that Bi6Ti2.8Fe1.52Mn0.68O18 thin films are both ferroelectric and ferromagnetic and, demonstrate magnetic field-induced switching of ferroelectric polarization in individual Aurivillius phase grains at room temperature

“…[8][9][10] Some work have been done in the incorporation of perovskite like SmFeO 3 , GdFeO 3 , DyFeO 3 , and LaFeO 3 ͑LFO͒ into BIT matrix. 11 However, one can find that the reported magnetic properties in these materials are quite weak even at low temperature ͑ϳ10 K͒. Some reported magnetic hysteresis loops are too narrow to be distinguished.…”

Highly crystalline quality c-axis epitaxial nLaFeO3–Bi4Ti3O12 (n=0.5,1.0,1.5) thin films were deposited on SrTiO3 (001) substrates by pulsed laser deposition. The x-ray diffraction and transmission electron microscopy characterizations confirm that there are designed even-odd number perovskite-block structures in n=0.5 and 1.5 films while it has even-even number ones in n=1.0 films. The remarkable physical property of n=0.5 and 1.5 samples is the presence of ferrimagnetism even up to room temperature. While it is antiferromagentic property in n=1.0 sample. The observed ferrimagentism is explained qualitatively by considering the crystal structure in nLaFeO3–Bi4Ti3O12.
