Author(s): C. Bidaud, O. Simard, G. Quirion, B. Prévost, S. Daneau, A. D. Bianchi, H. A. Dabkowska, and J. A. Quilliam In this work, the ultrasound velocity is measured in the frustrated spin liquid material SrDy 2 O 4 as a function of magnetic field and temperature. Experimental data reveals a complex phase diagram that depends heavily on the direction of the magnetic field. Whereas a dome for the three-dimensional long-range magnetic order is induced for magnetic field applied along the b axis, no finite temperature magnetic order is observed for other field directions. When passing between the spin liquid and magnetically ordered phase, significant irreversibility is observed. “Solidification” of the spin liquid (through applied field) proceeds through three distinct steps while melting of the magnetic order into the spin-liquid phase is a more continuous process.
