Experiments carried out with the use of ultrasonic technique in doped crystals have established three mechanisms relaxation Jahn-Teller subsystem at low temperatures. All them a quantum nature. The Debye function ${f}_{D}=1/(1+i\ensuremath{\omega}\ensuremath{\tau})$ is changed due to temperature-dependent time $\ensuremath{\tau}(T)$ provided frequency $\ensuremath{\omega}$ fixed. dependence derived an experiment on dissipation or/and dispersion wave makes it possible obtain temperature...
Abstract The present work is an ultrasonic study of the temperature dependence dynamic elastic moduli in single crystal BaF 2 doped with Cu. Similar to observation CaF :Cu 2+ , real and imaginary parts modulus c 44 manifest typical anomalies, which are induced by Jahn-Teller effect T ⊗ ( e + t ) case orthorhombic or trigonal stable structures. However, :Cu, these anomalies much smaller than . We attribute this difference lower concentration Cu dopants that isovalently replace Ba matrix. Our...
Using the example of developed “Biotechnical systems and technologies” master educational program ability to develop students’ innovative activity through implementation in practice interdisciplinary commercial projects using production base modern innovation centers Federal University is demonstrated. Such an organization activities marked a pronounced practice-oriented orientation education, allowed undergraduates certain entrepreneurial skills, improved perception material. Based on...
