The practical value of the study

Scientific results:

  1. For the first time at room temperature we were able to observe magnonic second noise or wave energy transfer and spin angular momentum in a quasi-equilibrium magnon gas that undergo Bose–Einstein condensation (BEC) in a ferrite film.
  2. We have proposed a method for exciting quasi-linear and nonlinear auto-oscillation magnetization modes by direct current in a nano-slot spin Hall nano-oscillator that uses a geometry with a widened gap. It has been demonstrated that the quasi-linear mode is stable at low excitation currents, while the non-linear mode is excited additionally at high currents and becomes more dominant as the current increases.
  3. The Laboratory has developed a technology for magnetron deposition of multi-layer metallic nano-structures with a perfect structure of layers and interfaces and produced [Co90Fe10/Cu]n  exchange-coupled super-lattices with a record value of magnetic resistance: 83% at room temperature and over 160% at helium temperatures. The obtained values of magnetic resistance set records for this composition of nano-lattices.
  4. Giant microwave magnetoresistance in [CoFe/Cu]n nanostructures has been researched in the millimeter wavelength range. The measurements were performed for super-latiices with maximum magnetoresistivity effect. We determined new field dependencies of the transmittance and reflection coefficients. We achieved a record-high change in the transmittance coefficient (up to 80%).
  5.  We have built a quantum theory of electron spin transfer in conducting magnetics that describes a whole range of new galvanomagnetic phenomena caused by the impact conductivity electrons on the spin that is created by spatially inhomogeneous magnetic fields and (or) the internal magnetic fields of a quantum exchange origin. We provided a description of two new spin transport effects in conducting chiral helimagnetics: the «electric magnetochiral Stern–Gerlach effect» and the «kinetic magnetochiral Stern–Gerlach effect». Our researchers have determined the conditions of the experimental observation of the phenomenon of resonance amplification of new effects that was named «magnetochiral kinetic resonance». 

Implemented results of research:

  1. We have developed Ta/NiFeCr/[CoFeNi/CuIn]n/Ta magnetic super-lattices with the effect of giant magnetic resistance (GMR) and unique properties: a high magnetic resistance, a low hysteresis, a high linearity of the characteristic, low magnetic saturation fields, a high sensitivity and temperature stability. In this class of magnetically sensitive nanomaterials the developed GMR super-lattices surpass foreign counterparts in terms of their functional characteristics. A batch of plates with sprayed GMR super-lattices has been manufactured and are currently produced by employees of the Laboratory in the interest of the Research and Production Complex «Technology center» (Zelenograd). GMR super-lattices are designed for creating innovative magnetoelectronic devices.
  2. In the interest of the Research and Production Association of Automatics (Yekaterinburg) we developed magnetic super-lattices with required functional characteristics. The produced magnetically sensitive materials have been used for the development of integrated detectors of high currents in electric transmission lines.

Education and career development:

  • Employees of the Laboratory have taught lecture courses at the Ural Federal University on the topics: «Additional chapters of physics», «Electrodynamics and mechanics of continuous media», «Physical kinetics», «Quantum transport in nanostructures».
  • One Candidate of Sciences and one Doctor of Sciences dissertations have been prepared and defended.
  • We have developed education courses for Russian universities, primarily for the Ural Federal University.
  • On the grounds of the Laboratory students of the Ural Federal University have prepared 4 bachelor’s degree and 2 master’s degree thesis.

Organizational and structural changes:

  • The Center for the Collective Use of Scientific Equipment «Department of Technologies and Diagnostics of Nanostructures» has been created on the basis of the Laboratory. It was incorporated into the Center for the Collective Use of Scientific Equipment «Testing Center for Nanotechnologies and Advanced Materials». The «Department of Technologies and Diagnostics of Nanostructures» possesses unique spraying, lithography and research equipment necessary for conducting works in the domain of nanotechnologies.
  • Some units of the Laboratory’s equipment became part of the Center for the Collective Use of Scientific Equipment «Physics and Technology Infrastructure Complex» of the Institute of Metals Physics of the Ural Branch of the Russian Academy of Sciences, which performs works for structural divisions of the Institute of Metals Physics of the Ural Branch of the Russian Academy of Sciences, institutes of the Russian Academy of Sciences, other science and education organizations, industrial enterprises, individual entrepreneurs and other entities conducting research in the area of the development of new materials and modern technologies.
