Title Neutron scattering studies of the spin ices Ho2Ti2O7 and Dy2Ti2O7 in applied magnetic field
Contributors
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 (&alpha;) and perpendicular (&beta;) 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.
