Ice-rule breaking spin-flip in a pyrochlore spin ice compound Dy2Ti2O7 has been studied in a field applied near the [112] direction, by means of angle-resolved magnetization measurements. We obtained strong evidence that the magnetization component perpendicular to the kagom? plane undergoes a first-order transition below ~0.26?K. This transition is driven by a ferromagnetic ordering in the field-decoupled spins on the triangular lattice in Dy2Ti2O7, as predicted theoretically.
