Temperature effects on magnetic properties of Fe3O4 nanoparticles synthesized by the sol-gel explosion-assisted method

Journal of Alloys and Compounds, 2019
Fe3O4 nanoparticles were successfully synthesized by the sol-gel explosion-assisted method. The phase composition of products with different ratios of dry gel and explosive agent (3:1, 6:1, 12:1) was studied. Highly pure, well-crystallized, spherical and

Magnetic properties of Sm0.1Ca0.9MnO3 nanoparticles

Journal of Applied Physics, 2012
Magnetic properties of compacted Sm0.1Ca0.9MnO3 nanoparticles with average particle size of 25 and 60 nm have been investigated. It was found that the relative volume of the ferromagnetic phase decreases with decreasing particle size. Magnetization curves measured in field cooled and zero field cooled mode separate near the transition temperature TC ...

Magnetic properties of MnCr2O4 nanoparticle

Journal of Magnetism and Magnetic Materials, 2010
Abstract The exchange interactions and the magnetic exchange energies are calculated by using the mean field theory and the probability law of Zn 1− x Mn x Cr 2 O 4 nanoparticles. The high-temperature series expansions have been applied in the spinels Zn 1− x Mn x Cr 2 O 4 systems, combined with the Pade approximants method, to ...
