Explore the light and magnetic rare earth


,[link widoczny dla zalogowanych], Successfully applied to the domestic industry,[link widoczny dla zalogowanych], research, and promote our growth as an international technology leader in the field of rare earth separation and the largest producer and applications are; they also based on relativistic density functional theory, developed a high-precision algorithm and related packages BDF (: BeijingDensityFunction),[link widoczny dla zalogowanych], as containing rare earth elements and other heavy elements provides the world's most accurate relativistic density functional calculation. Into the laboratory, we can see a variety of shapes, flashing lights of different colors of large instruments for measurement of polycrystalline and single crystal structures of multiple X-ray diffraction, for the preparation of high-performance light-emitting devices vacuum thin film deposition systems for the measurement of surface structure and composition of the tunnel scanning detection system for measuring the ability of molecular structure and bonding of multiple IR systems for a variety of materials prepared by vacuum sputtering and plasma sputtering radio system for the preparation of different systems of high temperature, vacuum synthesis system, as well as for measuring the optical properties of sets of spectral systems. Laboratory, optical and magnetic characterization measurements with good conditions. One set of instruments 3m long attracted attention, this is fluorescence spectroscopy of rare earth materials have a very important feature is the ability to fluoresce. Ray fluorescence spectrometer is to hit the rare earth material samples to detect visible light emitted by the sample's wavelength and intensity. The performance of different wavelengths of light into different colors such as red, green and so on, different colors of light can distinguish objects in the mark up. Luminescent materials in biomedical research is also important, the surface treatment of rare earth luminescent materials injected into the living body, you can see the emitted light rare earth materials organisms need to know about the structure and composition information. Rare earth materials in addition to the characteristics of light, the other a very important feature is that it has a strong magnetic, here called the magnetic measurement system with instruments used to detect the rare earth magnetic materials. This set of instruments the use of superconducting magnetic field generated by magnetic measurements of rare earth materials. It can measure the 2-300K characterization of various magnetic materials, but also can control the sample temperature, measured under different temperatures and magnetic field the magnetic properties. The instrument measured a very high degree of precision, can be observed extremely weak magnetic signals. Application of rare earth magnetic material is very extensive and important, such as now used in a variety of permanent magnetic material on the machine are made from the rare earth materials. The laboratory focuses on basic research on rare earth materials, hoping to find some good prospects for magnetic materials applications. Application of Rare Earth Materials Chemistry and State Key Laboratory of Rare Earth Chemistry, Peking University is in the original research centers and Department of Chemistry, Inorganic Chemistry of rare earth luminescent materials based on the established group. Inorganic Chemistry Laboratory of Rare Earth Chemistry and physics with chemistry, separation chemistry,[link widoczny dla zalogowanych], molecular spectroscopy, bio-inorganic chemistry, quantum chemistry and solid chemistry and chemical bond theory and so have a good academic accumulation and research features. Italian scientists *** Lei singular magnetic neptunium dioxide mystery. For a long time, neptunium dioxide (NpO2) has not been the singular magnetic scientific explanation. Germany and Italy, researchers calculated by theory, the singular magnetic neptunium dioxide may result from the formation of the magnetic atoms to ask 32 very moment. Neptunium is a transuranium element. Typically, people only concerned about the radioactive transuranic elements, but are transuranium actinide elements there is another element of a unique nature - the very complex structure of the outer electron cloud. Because of this special structure, the interaction between the atoms may cause unusual phenomena, the researchers discovered neptunium dioxide has a very special,[link widoczny dla zalogowanych], never before seen a strange magnetism. Iron and other ferromagnetic materials is a magnetic moment of atoms, each atom as an Arctic and Antarctic
