Title: Interplay of dilution and magnetic field in the nearest-neighbor spin-ice model on the pyrochlore lattice,
Abstract: We study the magnetic field effects on the diluted spin-ice materials using
the replica-exchange Monte Carlo simulation. We observe five plateaus in the
magnetization curve of the diluted nearest-neighbor spin-ice model on the
pyrochlore lattice when a magnetic field is applied in the [111] direction.
This is in contrast to the case of the pure model with two plateaus. The origin
of five plateaus is investigated from the spin configuration of two
corner-sharing tetrahedra in the case of the diluted model.
