Effect of lattice strain on structural and magnetic properties of Ca substituted barium hexaferrite
Sunil Kumar,Sweety Supriya,Rabichandra Pandey,Lagen Kumar Pradhan,Rakesh Kumar Singh,Manoranjan Kar +5 more
TL;DR: In this paper, a correlation between magnetic interaction and lattice strain has been observed in Ca2+ substituted M-type barium hexaferrite, which could be due to decrease of magnetic exchange interaction (Fe-O-Fe) in the sample.

Lattice strain mediated dielectric and magnetic properties in La doped barium hexaferrite
Sunil Kumar,Murli Kumar Manglam,Sweety Supriya,Harendra Kumar Satyapal,Rakesh Kumar Singh,Manoranjan Kar +5 more
TL;DR: In this paper, the La3+doped M-type barium hexaferrite (Ba1−xLaxFe12O19) with x 0, 0.15, 0, and 0.20 have been prepared by the sol-gel technique.

Effect of doping different rare earth ions on microstructural, optical, and magnetic properties of nickel-cobalt ferrite nanoparticles
TL;DR: In this article, the influence of doping different rare earth ions (Gd3+, Sm3+, and Eu3+) on the structural, optical, and magnetic properties of Ni-Co spinel ferrite nanoparticles synthesized via chemical co-precipitation method was investigated.
