Abstract
Resistivity, magnetization and electron tunneling measurements have been performed on single crystal YB 6 at low temperatures. It is found to be a type II superconductor with gap parameter 2Δ kTc = 3.8 and with a main phonon peak at an energy of 11 meV. Strong electron coupling with this mode, which is believed to be an Einstein-like mode associated with the Y ion, is though to be the common origin of the superconductivity and the behaviour of the electrical resistance in YB 6.
