Resonant driving of magnetization precession in a ferromagnetic layer by coherent monochromatic phonons

We realize resonant driving of the magnetization precession by monochromatic phonons in a thin ferromagnetic layer embedded into a phononic Fabry-Pérot resonator. A femtosecond laser pulse excites resonant phonon modes of the structure in the 10−40 GHz frequency range. By applying an external magnetic field, we tune the precession frequency relative to the frequency of the phonons localized in the cavity and observe an enormous increase in the amplitude of the magnetization precession when the frequencies of free magnetization precession and phonons localized in the cavity are equal

INTERDISCIPLINARY CLINICAL PRACTICE GUIDELINES "MANAGEMENT of OBESITY and ITS COMORBIDITIES" [МЕЖДИСЦИПЛИНАРНЫЕ КЛИНИЧЕСКИЕ РЕКОМЕНДАЦИИ «ЛЕЧЕНИЕ ОЖИРЕНИЯ И КОМОРБИДНЫХ ЗАБОЛЕВАНИЙ»]

Clinical guidelines have long been one of the working tools of the modern doctor, helping him quickly navigate the most effective proven methods of treatment and prevention of various diseases, and also to adapt these methods to the specific tasks of their patients and to achieve maximum personalization of treatment. Clinical practice guidelines are drawn up by professional non-profit associations and are approved by the Scientific Council of the Ministry of Health of the Russian Federation, while often one recommendation is prepared by two or even three associations. The peculiarity of the recommendations offered to your attention is that not only endocrinologists, but also therapists, cardiologists, gynecologists, gastroenterologists, and experts of many other specialties are involved in the prevention and treatment of obesity. The Multidisciplinary Working Group presents this a project in a multidisciplinary journal to bring together the efforts of several professional associations that associated with the need to pay attention not only to obesity itself but also to comorbid conditions. We are looking forward to constructive criticism and a comprehensive discussion of the problem on the pages of our journal. © 2021 Russian Association of Endocrinologists. All rights reserved
