Magnetic Properties of Co73Fe4Si12B11 Ferromagnetic Microwires in Amorphous and Crystalline State
We studied the magnetic properties of Co73Fe4Si12B11 ferromagnetic microwires in initial amorphous and crystalline state achieved by thermal treatment with direct current. A microwire in amorphous state is found to be characterized with quasilinear hysteresis loop with small coercive force less than 0.05 kA/m. Once crystallized, the microwire loses its soft magnetic properties, its hysteresis loop radically expands, and the coercive force becomes equal to 15 kA/m.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
