Effects of iron concentrations on the electrical properties of La0.67Ba0.33Mn1−xFexO3

Electrical conductance and complex impedance analysis of La0.6Pr0.1Ba0.3Mn1−xNixO3 nanocrystalline manganites

“…The E a values estimated from the slope of the linear fit plot increase from 37 meV for x = 0 to 48 meV for x = 0.1. The same behavior was observed in previous works, where Mn was substituted by Sn [9], Fe [24] and Ni [25].…”

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

“…In the last few years, various researches [14][15][16] have suggested that doping at Mn-site influences the polaronic transport. 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].…”

“…The most observed mechanisms are hopping and percolation ones. Recently, we have investigated the iron effects in the electrical properties of LaBaMnO 3 system [22]. On one hand, we found that electrical properties are strongly dependent on the iron content.…”

Effect of chromium concentration on the structural, magnetic and electrical properties of praseodymium-calcium manganite

“…Various researches [28,29,30] have suggested that doping at Mn-site influences the polaronic transport. The effect of substituting manganese ion by different element such as tin, iron, chromium and titanium is well studied [31,32,33,34,35,36]. When modifying the dopant element, its concentration and the substitution sites, different conduction mechanisms appear.…”
