“…Magnetic field-dependent dielectric resonance effects have been seen in nanoporous silicon , and La 2/3 Ca 1/3 MnO 3 consistent with expectations from the generalization of the Maxwell–Wagner capacitor model . Magneto-dielectric coupling has also been reported in phase-separated media, − but there has been no direct evidence of magnetocapacitance yet reported in these systems. More direct experimental validation of magnetocapacitance effects have been observed in nonmultiferroic graphene oxide, metal to semiconductor interfaces, and complex oxides.…”

We report the observation of a magnetocapacitance effect at the interface between Ni and epitaxial nonpolar BiInO 3 thin films at room temperature. A detailed surface study using X-ray photoelectron spectroscopy (XPS) reveals the formation of an intermetallic Ni−Bi alloy at the Ni/BiInO 3 interface and a shift in the Bi 4f and In 3d core levels to higher binding energies with increasing Ni thickness. The latter infers band bending in BiInO 3 , corresponding to the formation of a p-type Schottky barrier. The current−voltage characteristics of the Ni/BiInO 3 /(Ba,Sr)RuO 3 / NdScO 3 (110) heterostructure show a significant dependence on the applied magnetic field and voltage cycling, which can be attributed to voltage-controlled band bending and spin-polarized charge accumulation in the vicinity of the Ni/BiInO 3 interface. The magnetocapacitance effect can be realized at room temperature without involving multiferroic materials.

This study aims to explain the dielectric relaxation in sodium silicate (Na2SiO3) and its direct dependence on temperature across various frequencies. The study examines and elucidates the involvement of various types of polarization in the thermo-active dielectric relaxation process. Both low-frequency dielectric dispersion and complex impedance play pivotal roles in controlling the thermo-active dielectric relaxation process. Utilizing complex data plots, the study actively, and prominently illustrates the relaxation process.
