Download and read online ebook Ultrafast Magnetization Dynamics of Magnetic Nanostructures write by Hassan Kesserwan. This book was released on 2011. Ultrafast Magnetization Dynamics of Magnetic Nanostructures available in PDF, EPUB and Kindle. Divided in two parts, this PhD thesis concerns the magnetization dynamics of magnetic nanoparticles. In the first part, we have described a detailed experimental study of the magnetization dynamics in core/shell CoPt nanoparticles. Towards that goal, we have performed Time Resolved Magneto-Optical Effect measurements using a femtosecond pump and probe set-up with pulse durations and wavelengths : pump 150 fs/400 nm and probe 150 fs/800 nm probe. We studied the different magneto-dynamical processes taking place on short time scales such as : the ultrafast demagnetization and the precession of the magnetization vector. The obtained results indicate a possibility of inducing a supra-crystalline ordering of the nanoparticles due to a mild laser annealing. We showed that there is an important influence of the thermal annealing on the magnetic properties of the nanoparticles. For example, it leads to a magnetic phase transition form super-paramagnetic to ferromagnetic above the room temperature. This ferromagnetism manifested itself as an increase in the magnetic anisotropy of the nanoparticles and in the precession of the magnetization vector induced by the pump pulses. The second part is devoted to the numerical simulations of the magnetization reversal in isolated and interacting nanoparticles. In isolated nanoparticles, the relaxation times follow the Arrhenius law provided by the Néel-Brown's model. To account for the magnetic dipolar interaction, we have introduced a simple and effective model based on the mean field approximation. In general, we have observed deviations from the Arrhenius law, and showed that the dipolar interaction accelerates the reversal process.

Download and read online ebook Atomic- and Nanoscale Magnetism write by Roland Wiesendanger. This book was released on 2018-11-02. Atomic- and Nanoscale Magnetism available in PDF, EPUB and Kindle. This book provides a comprehensive overview of the fascinating recent developments in atomic- and nanoscale magnetism, including the physics of individual magnetic adatoms and single spins, the synthesis of molecular magnets for spintronic applications, and the magnetic properties of small clusters as well as non-collinear spin textures, such as spin spirals and magnetic skyrmions in ultrathin films and nanostructures. Starting from the level of atomic-scale magnetic interactions, the book addresses the emergence of many-body states in quantum magnetism and complex spin states resulting from the competition of such interactions, both experimentally and theoretically. It also introduces novel microscopic and spectroscopic techniques to reveal the exciting physics of magnetic adatom arrays and nanostructures at ultimate spatial and temporal resolution and demonstrates their applications using various insightful examples. The book is intended for researchers and graduate students interested in recent developments of one of the most fascinating fields of condensed matter physics.
