Silica glasses exposed to steady-state and pulsed irradiation with Fe+ ions are studied using magnetic resonance. The irradiation doses used in experiments are equal to 1 x 10(15), 1 x 10(16), and 1 x 10(17) cm(-2). It is found that, under both steady-state and pulsed irradiation conditions, glass samples exposed at a dose of 1 x 10(17) cm(-2) exhibit a broadband orientation-dependent signal. The shape of inclusions is evaluated under the assumption that the observed spectrum is caused by the ferromagnetic resonance induced in a new phase of metallic iron.
