Abstract

The electroresistance relaxation in the Bi, Yb, Be, Mn amorphous films is investigated at low temperatures. It is shown that this process is, as a rule, a exponential process with a unique characteristic relaxation time. There occurs a subbarrier tunneling of the hydrogen atoms in the metal√hydrogen amorphous films. We believe that this is responsible, in particular, for the delay in originating the superconductivity at T=4.2 K upon completion of the condensation of the Be√H amorphous films.
