Transformation of structure and magnetic properties of Cu2MnBO5 under partial Mn3+ -> Fe3+ substitution
Single crystals of Fe-substituted Cu(2)Mn(1-x)FexBO(5) ludwigites have been synthesized using flux technique (x = 0.2, 0.4, 0.5 - in the initial flux system). Structural properties of the synthesized compounds were studied ...
Magnetic resonance studies of mixed chalcospinel CuCr2SxSe4−x (x = 0; 2) and CoxCu1−xCr2S4 (x = 0.1; 0.2) nanocrystals with strong interparticle interactions
Magnetic resonance characteristics of mixed chalcospinel nanocrystals CuCr2SxSe4−x (x = 0 and 2) and CoxCu1−xCr2S4 (x = 0.1 and 0.2) have been investigated. It has been established based on TEM, SEM and resonance data that ...
Magneto-transport phenomena in metal/SiO2/n(p)-Si hybrid structures
Present review touches upon a subject of magnetotransport phenomena in hybrid structures which consist of ferromagnetic or nonmagnetic metal layer, layer of silicon oxide and silicon substrate with n- or p-type conductivity. ...
Chemical disorder reinforces magnetic order in ludwigite (Ni,Mn)(3)BO5 with Mn4+ inclusion
Crystals of ludwigite Ni2.14Mn0.86BO5 were synthesized by flux growth technique and contain Mn3+ and Mn4+. A possible mechanism of the manganese valence states stabilization has been proposed. The structural and magnetic ...
