Multiferroics—materials which are simultaneously (ferro) magnetic and ferroelectric, and
often also ferroelastic—attract now considerable attention, both because of the interesting …

In this contribution to the special issue on multiferroics we focus on multiferroicity driven by
different forms of charge ordering. We will present the generic mechanisms by which charge …

Transition metal oxides with a perovskite-type structure constitute a large group of
compounds with interesting properties. Among them are materials such as the prototypical …

The development of electronic technology is flexibly related to the progresses made in
material science. Functional materials out of the broad class of materials available today …

We report the detailed study of dielectric response of Pr 0.6 Ca 0.4 Mn O 3 (PCMO), a
member of the manganite family showing colossal magnetoresistance. Measurements have …

The complex impedance of a Pr 0.67 Ca 0.33 MnO 3 crystal has been measured. The
frequency dependence is studied for a wide range of temperatures (50–403 K) and is found …

We report the dielectric response of La1. 5Sr0. 5NiO4, a system that experiences charge
ordering above room temperature TCO= 480 K and a rearrangement of its charge-order …

Low-temperature (23⩽ T⩽ 150 K) dielectric properties of Pr 1− x Ca x MnO 3 (PCMO)(0.1⩽
x⩽ 0.9) were investigated systematically. A thermally activated relaxation was found in both …

The magnetic and transport properties of (Pr 1/3 Sm 2/3) 2/3 A 1/3 MnO 3 (A= Ca, Sr and Ba)
compounds, prepared by the citrate-gel route, have been investigated. These compounds …

Abstract Ca 2− x Pr x MnO 4 (0≤ x≤ 0.2) polycrystalline ceramic powders were synthesized
by sol–gel method. The X-ray diffraction (XRD) profiles were indexed with a tetragonal and …
