Magnetic, magnetodielectric, and magnetoimpedance correlations in co-substituted (Co, Ho) KBiFe2O5 at room temperature

Multiferroic Properties of Co, Ru, and La Ion Doped KBiFe2O5

“…The dielectric constant ϵ decreases with increasing h. The magneto-dielectric coupling MD(%) = (ϵ(h) − ϵ(0))/ϵ(0) is negative, where ϵ(h) and ϵ(0) are the dielectric constant with and without magnetic field, respectively. This is in agreement with the experimental data of Khan et al [27] and Chandra et al [15,17].…”

“…Let us emphasize that codoping, for example with Ru and Co, would show a stronger increase in M and P or decrease in E g than the Ru-or Co-doped compounds. Recently, the codoping effects of different ions on the properties of KBFO were studied in [17]. These effects will be studied in a next paper.…”

“…The doping effects with different ions (La, Y, Co, Ho, Ru, and Al) on structural, magnetic, electrical, and optical properties of KBFO have also been investigated [13][14][15][16][17][18]. The doping ions can change the properties of the compound.…”

Investigation of the structural, surface topographical, fractal, capacitive, and electrical properties of a defect brownmillerite perovskite material KBiFeMnO5 for electronic devices

“…10 The brownmillerite material KBiFe 2 O 5 (KBFO) has urged a special focus on photovoltaic, magnetoelectric, and electronic device applications. [11][12][13] Manganese (Mn) substitution is particularly appealing because it not only substantially reduces leakage current but also triggers a residual magnetization in bismuth ferrite (BFO). 14 The incorporation of manganese (Mn) at the iron (Fe) site in bismuth ferrite (BiFeO 3 ) has been investigated to achieve a mixed valence state of iron involving both Fe 3+ and Fe 2+ .…”
