中文摘要	High quality single crystals of heavy Fermion CeCoIn5 superconductor have been grown by flux method with a typical size of (1 - 2) x (1 - 2) x (similar to 0.1) mm(3). The single crystals are characterized by structural analysis from x-ray diffraction and Laue diffraction, as well as compositional analysis. Magnetic and electrical measurements on the single crystals show a sharp superconducting transition with a transition temperature at T-c, onset similar to 2.3K and a transition width of similar to 0.15 K. The resistivity of the CeCoIn5 crystal exhibits a hump at similar to 45 K, which is typical of a heavy Fermion system. High resolution angle-resolved photoemission spectroscopy (ARPES) measurements of CeCoIn5 reveal clear Fermi surface sheets that are consistent with the band structure calculations when assuming itinerant Ce 4f electrons at low temperature. This work provides important information on the electronic structure of heavy Fermion CeCoIn5 superconductor. It also lays a foundation for further studies on the physical properties and superconducting mechanism of the heavy Fermion superconductors.
