The pressure and magnetic field phase diagram of SrCu2(BO3)2.

Caption

(a) The zero-field pressure-temperature (P-T) phase diagram. (b-g) The T-linear specific heat region (red area) is concentrated near the zero-field first-order PS–AF transition pressure, highlighting the role of pressure and magnetic field in stabilizing the new low-energy response state. (h)The pressure–magnetic field phase diagram of SrCu2(BO3)2 at 0.4 K summarizes the evolution of distinct magnetic ground states under external tuning.
