Influence of iron substitution on the ferromagnetic ordering and magnetic entropy variation in La1-Na Mn1-Fe O3 (x = 0.1, 0.2 and y = 0, 0.1)

Crystal structure, composition and valence state of cations in mixed-valence A1−xCdxMnO3 (A=Pr, La) ceramics

“…The initial interest in these compounds stemmed from the discovery of a colossal magnetoresistance effect [3][4][5][6]. Later, a variety of intriguing magnetic and electrical effects were uncovered in these compounds [7][8][9][10][11][12][13][14][15][16], including the observation of both positive and negative temperature resistance coefficients [17], metal-insulator transitions [18], ferromagnetic-paramagnetic transitions [19,20], and charge ordering [21,22]. These properties make these materials promising for use in magnetic sensors [23], supercapacitors [24], and infrared bolometers [25,26].…”

Influence of Fe3+ ion substitution on Structural, Magnetic Properties and Magnetoresistance Effect of Pr0.75Na0.05K0.20MnO3 System

“…According to studies, different substitutions of manganite systems exhibit different mechanisms and properties [9,16,17]. Among that, Fe substitution was reported to contribute to mixed phases of AFM clusters in the FM matrix [18,19]. As a result, it is intriguing to investigate the effect of Fe in Pr 0.75 Na 0.05 K 0.20 MnO 3 manganites.…”
