“…It can be seen the criteria R-factors are all less than 10.0%, which suggests that the refinements are successfully performed. The BiFeO 3 ceramic before nitrating has two phases (BiFeO 3 , Bi 25 FeO 40 ) with the content of 95.59% and 4.41% respectively, and Bi 25 FeO 40 has a sillenite structure of cubic symmetry with the space group of I23 [25]. After nitrating, only BiFeO 3 phase is detected in the XRD pattern even if under the hyperslow scanning speed, which confirms the impurity phase has been decomposed completely in the accuracy of our experiments.…”

“…It is clearly seen that some white phases are dispersed in the microstructures and most of them are on the boundary of gray phases. EDS quantitative analysis results show that white and gray phases are Bi-rich Bi 25 FeO 40 phase and BiFeO 3 phase, respectively. Some bright regions in the EDS mapping represent very great concentration of Bi element, which indicates the existence of Bi-rich Bi 25 FeO 40 phase as shown in BSE image.…”

“…These results indicate that the grain growth of Bi 25 FeO 40 impurity may be suppressed, which could reduce the stability of such impurity phase.

order parameters would lead to switching of the electrical polarization ( P ) by the magnetic fi eld H , or the magnetization ( M ) by the electric fi eld E , which has been proposed as a possible candidate to replace the presently used volatile random access memories (RAM). [ 3,4 ] A magnetoelectric multiferroic memory would benefi t from nonvolatility and nondestructive reading of magnetic RAM and the lowpower, high-speed features of ferroelectric RAM. [ 3,4 ] Bulk BiFeO 3 exhibits both ferroelectric and long-range magnetic order at room temperature, however it is a pure antiferromagnet because the cycloidal magnetic ordering leads to cancellation of the Dzyaloshinsky-Moriya interactionmediated canted moments, and also prevents any linear magnetoelectric effect. [5][6][7][8] The cycloidal ordering can be destabilized in strained and nanostructured fi lms of BiFeO 3 leading to fi nite magnetization. [ 9,10 ] Electric fi eld-induced switching of the magnetization of a ferromagnetic layer coupled to BiFeO 3 has been demonstrated in thin fi lm devices. [ 10,11 ] Powder neutron diffraction (PND) and Möss-bauer studies show that PbFe 0.5 Ta 0.5 O 3 , PbFe 0 .5 Ta 0.5 O 3 -PbTiO 3 solid solution, and the Aurivillius phases Bi n +1 Fe n −3 Ti 3 O 3 n +3 (3.5 ≤ n ≤ 7) are not long-range magnetically ordered at room temperature: [12][13][14][15] ( n = 5) at room temperature. [ 16,17 ] Recently, we have reported a generic design route for room temperature multiferroic materials that integrates a percolating network of magnetic ions to produce long-range magnetic order with enhanced ferroelectric switching properties at the morphotropic phase boundary (MPB) between two polar phases with different polarization directions. This was exemplifi ed in the perovskite oxide (1− x )BiTi (1− y )/2 Fe y Mg (1− y )/2 O 3 -x CaTiO 3 (BTFM-CTO) system, using techniques that defi nitively proved the coexistence and switchability of both orders within the perovskite structure. [ 18 ] The order parameters are not only switchable at room temperature but are also coupled as demonstrated by the linear magnetoelectric effect. [ 18 ] The structure of the perovskite at the MPB is complex and has been the subject of detailed studies over Controlling Phase Assemblage in a Complex

Manganese and iron doped cadmium gallate has been synthesized by sol–gel approach. PXRD pattern shows the cubic arrangement of cadmium gallate spinel. Raman spectrum concludes the complete structural analysis of undoped and doped samples. Additionally, morphology and elemental ratio is obtained using FESEM and EDS spectroscopy. Blue indigo and green emission bands are shown in photoluminescence spectra. An excellent antiferromagnetic and ferromagnetic behavior of manganese and iron doped cadmium gallate are shown in the magnetic study. Low band gap of doped samples has made this material as a prominent catalyst for the degradation of methylene blue dye when exposed to UV–visible irradiation.
