For the case of the c 66 mode with ε x y, the Cu-O-Cu angle of the horizontal (vertical) dimer decreases (increases), leading to the reduced (enhanced) AFM interaction. Depending on the elastic modes ( c 66 and c 11), the exchange modulation acts on dimers asymmetrically and symmetrically, respectively (Fig. In SCBO, strain modulates the Cu-O-Cu angle and exchange coupling of the dimers, leading to a modulation of the magnetic free energy. The elastic constant is the second derivative of the free energy with respect to the strain. The sound velocity v is a thermodynamical quantity, related to the elastic constant c, as c = ρ v 2. Finally, saturation is reached at 137 T, in close agreement with the experimental values of H c9.įirst, we quantitatively discuss the drastic sound-velocity change of the c 66 mode. The transition into the period-14 SSP occurs around 128 T which coincides with H c8. The transition between the two 1/3 SSPs is found at 122 T (there is no anomaly observed in experiments at this value which could be because the two 1/3 SSPs are very similar states). The location of this transition is compatible with H c6 from the magnetostriction and magnetization measurements. Converted to real units 3, we find that the 1/2 plateau terminates at 106 T, with a jump in magnetization to the extremely narrow period-10 SSP, followed by the 1/3 SSP. The competing antiferromagnetic (AFM) couplings ( J and \(/J=0.63\) together with the energy differences of the competing states is shown, where the vertical dashed lines indicate the phase boundaries. The unveiled nature of this paradigmatic quantum system is a new milestone for exploring exotic quantum states of matter emerging in extreme conditions. Quite remarkably, the sound velocity of the 1/2 plateau exhibits a drastic decrease of -50%, related to the tetragonal-to-orthorhombic instability of the checkerboard-type magnon crystal. Using ultrasound and magnetostriction techniques combined with extensive tensor-network calculations (iPEPS), several spin-supersolid phases are revealed between the 1/2 plateau and saturation (1/1 plateau). Here, we report the first experimental and theoretical investigation of this compound up to the saturation magnetic field of 140 T and beyond. The discovery of a sequence of fractional magnetization plateaus in the Shastry-Sutherland compound SrCu 2(BO 3) 2 has played a central role in the high-field research on quantum materials, but so far this system could only be probed up to half the saturation value of the magnetization. Under magnetic fields, quantum magnets often undergo exotic phase transitions with various kinds of order.
