Аннотация:The nature of the field dependence of thermopower in the Co-Al-O and Fe-Al-O magnetic granular alloys with tunneling conduction is shown to be related to tunneling thermopower. The tunneling thermopower is small and depends approximately linearly on temperature and squared magnetization, and its field dependence is described by a relation of the type S(H)/T = a + brho(0)/rho(H), where rho is the alloy electrical resistivity and the parameters a and b are field-independent.
