Soft-magnetic amorphous alloys based on the ferromagnetic elements Fe, Co, Ni and their combination have attracted increasing interests since the discovery of the Fe-P-C system in 1967, because of their excellent soft-magnetic performances including high saturation flux density (Bs), low coercivity (Hc), high permeability, low core loss, and so on. By devoting subsequent great efforts, a variety of...
The Finemet alloy is used to make transformers for its excellent soft magnetic property. In order to study its distinctive character, it is essential to clarify the structural evolution mechanism especially in early nanocrystallization. The Fe73.5Si13.5B9Nb3Cu1 amorphous ribbons were prepared by single-roller melt-spinning process under argon atmosphere, and then annealed at 350??C, 380??C and 400??C...
This paper reports on magnetic properties of bulk polycrystalline samples of ln2O3 doped with a wide range of TM ions. Phase purity of the samples was analyzed by means of X-ray diffraction and conductivity was also measured using a four-probe technique. From magnetization-temperature curves (M-T curves), it was shown that Cr doped samples was found to be paramagnetic throughout the whole temperature...
