چکیده انگلیسی
The temperature and magnetic field behavior of non-uniform diamagnetic phase in Be is analyzed theoretically. It is shown, that in the model of slightly corrugated cylinder-like Fermi surface sheet relevant for dHvA oscillations in Be, the parameters of Condon domain (CD) phase, e.g. the magnetic induction splitting between two adjacent domains and the range of existence of non-uniform phase in every period of dHvA oscillations, reveal strong dependencies on temperature, magnetic field and purity of the sample. In particular, we show that the maximum of magnetic induction splitting â¼15mT can be achieved in Be at relatively moderate values of magnetic field μ0Hâ¼5-7 T and Dingle temperature TD=2K in contrast to the case of noble metals, e.g. Ag, where for observation of the splitting of the same order of values the extremely high magnetic field μ0Hâ¼35T and extremely pure samples with TD=0.1K are needed. The last circumstance can make it favorable to investigate experimentally the predicted temperature and magnetic field properties of CD phase in Be.
