Structural and magnetic properties of the double perovskite LaKFeMoO6 compound

Structural, magnetic and electrical transport properties of Co doping in LaKFeMoO6 double perovskite

“…3 that the magnetization reduces slowly with temperature warming from 80 to 300 K and no transition temperature is observed in this temperature range. This indicates that the Curie temperatures of Co-doped samples are higher than 300 K. In order to compare the magnetization of these compounds with that of the Co-undoped compound, the thermal magnetization curve of LaKFeMoO 6 compound obtained from literature [10] is also shown in Fig. 3.…”

“…Sr atoms have been replaced completely by Ca or Ba atoms, leading to different modifications of the physical properties [8,9]. Perhaps the most significant changes have been described for the LaKFeMoO 6 , in which MR increases to nearly 80% at 80 K [10]. However, unwanted antisite magnetic frustration and/or disordering effect are promoted, in such a way that the saturation magnetization dramatically decreases.…”

Crystal structural, magnetic and electrical transport properties of CeKFeMoO6 double perovskite

“…With La 3 + or K + doping in DP A 2 FeMoO 6 compounds (where A is the alkalineearth metal) carrier doping is inevitable in these materials. In order to figure out some effects without changing ionic valence states of B 0 and B 00 sites by A-site doping, we have studied the structural, magnetic and electrical transport properties and magnetoresistance of LaKFeMoO 6 compound and it shows low magnetic moment, large resistivity and magnetoresistance [11]. In order to improve the magnetic moment of LaKFeMoO 6 , the La 3 + is replaced by magnetic Ce 3 + ion in compound LaKFeMoO 6 .…”
