Abstract Double perovskites R 2 NiMnO 6 (R= Rare earth element)(RNMO) are a significant
class of materials owing to their varied tunability of the magnetic and electrical properties …

The research on electrochemical double layer capacitors (EDLC), also known as
supercapacitors or ultracapacitors, is quickly expanding because their power delivery …

The existence of a magnetodielectric (magnetocapacitance) effect is often used as a test for
multiferroic behavior in new material systems. However, strong magnetodielectric effects can …

Many transition-metal oxides show very large (“colossal”) magnitudes of the dielectric
constant and thus have immense potential for applications in modern microelectronics and …

In this review, an overview of acoustic-and radio-frequency frequency dielectric properties of
multiferroic oxides, the significant dynamic response of electrical polarization to small …

Polycrystalline LaFeO3 was prepared by the conventional solid-state reactions route. X-ray
diffraction was applied to check the phase formation. The Fe57 Mössbauer spectrum …

In the present work, we provide broadband dielectric spectra showing strong electrode
polarization effects for various materials, belonging to very different material classes. This …

Development of microelectronic devices is driven by a large demand for faster and smaller
systems. In the near future, colossal permittivity in nanomaterials will play a key role in the …

Polarons, the combined motion of electrons in a cloth of their lattice distortions, are a key
transport feature in doped manganites. To develop a profound understanding of the colossal …

Multiferroic materials are those which possess both ferroelectric and ferromagnetic
properties. Clearly, there is a contradiction here since ferromagnetism requires d-electrons …
