Abstract	Neutron diffraction has been used to investigate the magnetic correlations in single crystals of the spin ice materials Ho<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> and Dy<sub>2</sub>Ti<sub>2</sub>O<sub>7</sub> in an external magnetic field applied along either the [001] or [11¯0] crystallographic directions. With the field applied along [001] a long range ordered ground state is selected from the spin ice manifold. With the field applied along [11¯0] the spin system is separated into parallel (α) and perpendicular (β) chains with respect to the field. This leads to partial ordering and the appearance of quasione- dimensional magnetic structures. In both field orientations this frustrated spin system is defined by the appearance of metastable states, magnetization plateaus and unusually slow, field regulated dynamics.
