Grain size effects on the magnetic properties of chemically synthesized Ni:Ni sub(3)C nanocomposites

The synthesis of Ni:Ni sub(3)C nanocomposites with grain sizes from 5 to 60 nm and Ni sub(3)C nanocomposites with grain sizes from 20 to 50 nm. are described. The room-temperature coercivity and remanence ration are measured in terms of Ni grain size. Room-temperature measurements show that the Ni s...

Zusammenfassung:The synthesis of Ni:Ni sub(3)C nanocomposites with grain sizes from 5 to 60 nm and Ni sub(3)C nanocomposites with grain sizes from 20 to 50 nm. are described. The room-temperature coercivity and remanence ration are measured in terms of Ni grain size. Room-temperature measurements show that the Ni sub(3)C affect the collective magnetic behavior through interactions of the Ni particles.
