The paper presents experimental results for the intermetallic compound Y_9Co_7 which is the first very weak itinerant ferromagnetic superconductor. The measurements of electrical resistivity, susceptibility, magnetization, specific heat, nuclear magnetic resonance, and other properties show the magnetic transition at T_C≈ 4.5 K and the onset of superconductivity at about T_S≈ 2.5 K, revealing the coexistence state within a temperature interval below T_S. A few of the results are shortly reviewed and discussed. We focus attention on our recent ultraviolet photoemission spectroscopy and their comparison with our band structure calculations. Interpretations are considered which take into account the characteristic structure of the compound and different possible types of magnetic ordering.
