Abstract
Laser nanostructuring is a powerful tool to produce different nanomaterials such as nanoparticles and surface relief structures. It was shown that pulsed laser ablation of thin 250 nm Fe film in acetone allows obtaining core-shell Fe@FeO nanoparticles with a mean size of 90 nm. Fabrication of femtosecond laser-induced periodic surface structures on a Si substrate surface with subsequent deposition of a NiFe/IrMn exchange-biased bilayer causes the appearance of an additional out-of-plane magnetization component with keeping exchange bias. Obtained nanomaterials look promising for designing magnetic biosensors with an improved detection limit.
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.
