Data for Paper "Field-induced tricritical phenomenon and multiple phases in DySb"

Single crystals of DySb were prepared by a tin flux technique, and its physical properties were carefully checked elsewhere. The [00l] direction of the single crystal is determined by an x-ray diffraction (XRD) method. The magnetization measurements, including the temperature- and field-dependent magnetization, were performed on a Quantum Design vibrating sample magnetometer (SQUID-VSM). In particular, the initial isothermal magnetizations with H//[001] were carried out in detail. Before each measurement, the temperature was set at room temperature. After being held for 2 min, the sample was cooled to the target temperature. The magnetic field was quenched in an oscillation mode in order to exclude the influence of a possible remaining field. In addition, a no-overshoot mode was applied to ensure the precision of magnetic field.
