Magnetization Of Sm-Fe-N Thin Films With In-Plane Anisotropy

Am-Fe-N films have been made by dc magnetron sputtering and heating in-situ in nitrogen atmosphere. It is observed that the anisotropy changes from perpendicular to in-plane by nitrogenation. The Curie temperature is about 380 K. Aspects of structure, hysterisis loops, initial magnetization curves and temperature dependence of coercivity are discussed. SQUID magnetometer was used to measure the...

Synthesis of Sm–Co and Sm–Co/Fe nanocrystals by reductive annealing of nanoparticles

We report here a simple route for the chemical synthesis of SmCo5 and Sm2Co17 single-phase and SmCo5/Fe composite nanocrystals by polyol reduction of metal precursors and subsequent calcium reductive annealing. Sm2O3 and Co nanoparticles were synthesized first, and nanocrystalline SmCo5 or Sm2Co17, compound with tunable composition was then obtained after the annealing. The composition of the c...

Production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying

In this research, the production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying was investigated and evaluated. Ferrotitanium (containing 70%Ti), titanium and graphite were used as the raw materials. Initial mixtures were milled in different time durations under the pure nitrogen atmosphere with the pressure of 5atm. The results showed that when N2 pressure is 5 at...
