Charge ordering and charge accumulation in magnetic spin-ice lattices — •Elena Y. Vedmedenko — Institute of Applied Physics, University of Hamburg Jungiusstr. 11, 20355 Hamburg, Germany

Dipolar spin ice has attracted much attention because of their intriguing ground state ordering and elementary excitation properties. We present the theoretical investigation of magnetic dipolar spin ice on periodic and aperiodic lattices. Especial attention is paid to the evolution and the distribution of excitations with magnetic charges as a function of magnetic field and magnetic potential. It is demonstrated that depending on the micromagnetic reversal mechanism in individual particles charge ordered states or charge accumulation can be observed.
