Plasma of Magnetic Monopoles in Kagome Spin Ice

Abstract

The monopole’s charge, concentration and the frequency of long-wavelength plasmon at the band-edges for the periodic arrays of 2D magnetic-Dirac plasma layers at low temperature (0.5K~2K) are studied. The charge decreases as applied field becomes strong, and increases with increasing temperature. The concentration decreases as applied field becomes strong. The frequency increases as the temperature rises, and decreases as the strength of applied field increases. The range of the frequency is 3.8 × 10 11 Hz ~ 3.5 × 10 12 Hz
