Monopole equilibration in spin ice

ORAL

Abstract

Spin ice shows remarkably rich behavior due to its monopole quasiparticles and coulombic interactions. In actual materials quantum tunneling provides millisecond spin flip times which bring out-of-equilibrium states into reach for experimental and computational study. Recently there has been interest in using neutrons and noise as probes of such behaviors. We present computational and experimental studies of the magnetic states in Dy2Ti2O7 under out-of-equilibrium conditions. These cover the feasibility of noise and neutron measurements to assess the states in the material under thermal and field quenching.
