It was designed cryostat for X-ray studies at low temperatures in the temperature range 70-300 K. Modified method of crystal field theory, it is theoretically studied the electronic spectra of transition ions, arranged in an octahedral ligand environment. We propose a method of spin charts, allowing to study the evolution of the spin states of metal ions under the influence of distortion of the octahedral complex of different symmetry. For the first time identified areas Mixed spin states within which the states with high and low spin serednim coexist with almost equal probabilities. The methods of density functional theory, calculations of the band structure and magnetic properties of iron nanowires with different lateral dimensions. It is shown that the structure of Fe1 and Fe9 imeyutgigantskuyu magnetic anisotropy energy. It is established that the nickel target magnetron sputtering in an argon atmosphere with a mixture of nitrogen are formed on a glass substrate nanokolonarnye ferromagnetic films consisting of nanofiber diameter 70 - 100 nm, which grow along the normal to the lining. It was revealed that the nitrogen concentration ~ 3 at.% In the films of Ni-N observed size effect: the particle size of less than 10 nm, the saturation magnetization decreases rapidly, and to ~ 0.5 nm film has no magnetic ordering. Found that the films namagnichevaniya Ni-N Ni-C i is anisotropic: the direction along the plane - light, along the direction normal to the plane - heavy. Product Description popup.authors Букін Г.В.
