Electric–dielectric properties and complex impedance analysis of La_0.5Ca_0.5−xAg_xMnO₃ manganites

Abstract

The electric and dielectric properties of La0.5Ca0.5−xAgxMnO3 (LCMO–Ag with x = 0 and x = 0.4) were investigated using the impedance spectroscopy technique.

Microstructural properties, dielectric behaviour, conduction mechanism, impedance, and electrical modulus of La0.65Ca0.25Sr0.1MnO3 manganite

“…The obtained results were similar to those reported for other work [41]. It can be seen an asymmetry of peak reflects the existence of a non-Debye type of relaxation phenomenon within the material [42,43].…”

Influence of polarization and iron content on the transport properties of praseodymium–barium manganite

“…The effect of substituting Mn by Sn, Fe, Cr and Ti is well studied by our group [17][18][19][20][21][22]. Also, the effects of introducing Ag in manganite-system on electric and dielectric properties are recently studied [23][24][25][26]. Different conduction mechanisms appear when changing the dopant element, its concentration and the substitution sites.…”

Effect of exceeding the concentration limit of solubility of silver in perovskites on the dielectric and electric properties of half doped lanthanum–calcium manganite

“…Recently, La 0.5 Ca 0.5 MnO 3 manganite have been the focus of scientific interest [21][22][23][24][25][26]. There are only few reports on the study of transport properties of Ag doped LCMO [27][28][29][30]. Once structural, magnetic and optical properties of calcium-lanthanum manganite are investigated and explained, researchers are interested to the study of the effect of doping at Ca site by Sr and Ag elements on the physical properties of these manganites [21,22,31].…”
