In SrDy2O4, the Dy3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric frustration. In zero field this compound appears to be magnetically disordered down to at least 0.05 K. Our recent heat capacity measurements indicated that a magnetic field applied along the [010] direction induces a very sharp transition at 20 kOe. The nature of the field-iduced phase remains unknown. We propose to use the WISH diffractometer to study the low T magnetic phases in a single crystal sample of SrDy2O4 as a function of the applied field. The process of field induced ordering in SrDy2O4 appears to be rather remarkable even in the context of the unusual phase transitions observed in other geometrically frustrated magnetic systems consisting of hexagons and triangles.
