Abstract
The specific heat of amorphous Ge films evaporated at room temperature shows a strong magnetic field dependence at very low temperatures (0.07 K < T < 1.5 K). This effect is quantitatively attributed to magnetic excitations arising from localized unpaired electronic states (dangling bonds). It is shown that other kinds of excitations, e.g., tunneling states known from other amorphous solids, do not contribute measurably to the specific heat.Keywords
