Kinetics of magnetoelectric coupling in bismuth ferrite (BiFeO3) with the substitution of aliovalent calcium ion is investigated. The resulting structural, dielectric, magnetic, and magnetoelectric (ME) coupling properties are explained in terms of chemical pressure originating from the substituent ion. Substitution of calcium finds to reduce the oxygen vacancies. Two important substitution concentrations...
Magnesium and nickel‐substituted ferrites belong to an important class of spinel ferrites with wide variety of applications. Herein, preparation and characterization of pure, single‐phase Ni–Mg ferrites using a cost‐effective method, which yield high‐quality nanosized particles with good chemical homogeneity, are reported. A series of NixMg(1−x)Fe2O4 nanocrystalline powders (x = 1,0.75,0.5,0.25,0)...
