Spin-Density Wave, Unconventional Magnetic and Thermal Transport Properties in Sr2−x(PbCl2)xCu(BO3)2
SrCu<sub>2</sub>(BO<sub>3</sub>)<sub>2</sub> (Sr-122) has attracted considerable interest as a quasi-two-dimensional S = 1/2 Heisenberg antiferromagnetic spin system with a Shastry-Sutherland lattice (SSL) structure. It features a Cu<sup>2+</sup> spin dimer ground state and exhibits intra-dimer Dzyaloshinskii-Moriya interactions, making Sr-122 a fascinating platform for studying quantum magnetic phenomena. In this study, we investigate the β-phase of SrCu<sub>2</sub>(BO<sub>3</sub>)<sub>2</sub> (β-Sr-212), which retains the same spin structure as Sr-122, to explore how the carrier concentration affects the spin gap. Our results show that increasing the doping levels in SrCu<sub>2</sub>(BO<sub>3</sub>)<sub>2</sub> modulates the magnetic properties and slightly suppresses the spin gap, offering new possibilities for tuning its quantum magnetic behavior.
