Investigation of dielectric and magnetic nature of Bi7Fe3Ti3O21

Room temperature photoluminescence of the Li2ZnTi3O8 spinel: Experimental and theoretical study

“…Furthermore, these materials are also known to be very useful in the ceramic pigment industry [5][6][7][8].…”

The thermal behavior of mixed-layer Aurivillius phase Bi13Fe5Ti6O39

“…The ac conductivity r ac (1/T) as a function of reciprocal temperature measured at a frequency of 500 kHz has a change of slope at temperatures above 800 K, which corresponds to the change of the conductivity mechanism in the Aurivillius phases with increasing temperature [20,32,34,35]. From the part of the r ac (1/T) plot above 800 K, which approximated by a straight line (see Fig.…”

“…The value of E M is a typical one for oxide materials, with electric conductivity determined, primarily, by oxygen vacancy movement [20,32,34,35]. The oxygen vacancies in the structure of bismuth-containing Aurivillius phases are created due to the partial evaporation of Bi 3?…”

“…The temperatures of the phase transition of Bi m?1 Fe m-3 Ti 3 O 3m?3 compounds into magnetically ordered state (Neel point) were observed in the range from 77 to 360 K [2,5,[20][21][22][23] and the temperatures of the hightemperature phase transition (Curie point) in the range from 923 to 1023 K [13,17,[24][25][26][27][28][29][30][31].…”

Novel Approaches for Genuine Single‐Phase Room Temperature Magnetoelectric Multiferroics

“…As a result, the saturated coercive field and the minimum electric field for ferroelectric hysteresis loop saturation tends to decrease as m increases. 97 Given that the layered nature of the Aurivillius phase materials also allows for the incorporation of significant amounts of magnetic ions with +3 to +5 oxidation states 98 Aurivillius phases with m=4 100 , and antiferromagnetism (80 to 300K) for m=6 101 and m=7 102 .…”
