Magnetic interactions in La0.7Sr0.3Mn1−Me O3 (Me=Ga, Fe, Cr) manganites

First-Principle Investigation of La0.7Ba0.3Mn(1-x)FexO3 Structural Properties Using CASTEP

“…Although, Fe 3+ ions do not participate in the double exchange interaction phenomenon towards Mn 3+ [39] . Thus, in line with Troyanchuk et al reports that the ferromagnetic double exchange interaction weakens and strengthens the super-exchange interaction that supports the antiferromagnetic coupling between Mn 4+ -O-Mn 4+ , Mn 4+ -O-Fe 3+ , and Fe 3+ -O-Fe 3+ [40] . The reduction of the double exchange interaction can be seen from the decrease in the bandwidth value [41] .…”

Synergistic effect of lattice, electronic and magnetic modulations on the thermoelectric behaviour of Cr-substituted La0.65Bi0.20Sr0.15CoO3

“…The large negative MR has earlier been reported for La 0.5 Sr 0.5 Co 0.8 Cr 0.2 O 3 at low temperature. 67 In the literature, it is also well documented that the antiferromagnetic (AFM) phase for the cobaltite system has a signicantly large value of resistivity compared to the ferromagnetic (FM) phase. 68,69 It has been shown that in some transition metal perovskites, substitution of Cr ions at Co sites favours the formation of AFM like regions inside the short-range ferromagnetic (FM) ordering; see ESI Fig.…”

Flux growth and phase diversity of the triple oxides of transition metals (Mn,Fe,Ga)2O3in multicomponent fluxes based on Bi2O3–MoO3–B2O3–Na2O

“…Transition metal oxides containing Mn, Fe and Ga cations, as base materials, are perspective for application owing to their diverse properties and various crystal structures. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] The wide structural variety of these compounds demonstrates significant differences in their physical properties (electric, magnetic, etc.). Therefore, special attention is paid to triple systems (Mn,Fe,Ga) 2 O 3 because of the possibility of controlling their properties by a gradual change in the cation composition both within individual phases and at the intersection of the boundaries in the phase diagram.…”
