Giant Microwave Absorption in Metallic Grains: Relaxation Mechanism
arXiv:cond-mat/9508057 · doi:10.1103/PhysRevLett.77.1958
Abstract
We show that the low frequency microwave absorption of an ensemble of small metallic grains at low temperatures is dominated by a mesoscopic relaxation mechanism. Giant positive magnetoresistance and very strong temperature dependence of the microwave conductivity is predicted.
