Crossbreeding between Experiment and Theory on Orthogonal Dimer Spin System
Open accessAbstract
We have investigated two-dimensional spin systems SrCu2(BO3)2 and Nd2BaZnO5, both of which have a unique topology that is equivalent to the Shastry-Sutherland lattice. The magnetization curve of SrCu2(BO3)2 reveals that, unlike 1/8 and 1/4 plateaux, a 1/3 plateau is very stable, surviving at least up to 69 T. The pressure dependence of susceptibility up to 10 kbar indicates that the pressure causes the system to approach the critical point to some other states. On the other hand, Nd2BaZnO5 with rather classical spins exhibits an antiferromagnetic long range ordering at 2.4 K. Finally, other experimental candidates of extended Shastry-Sutherland system will be briefly presented.

The increase of C with dropping temperature might be caused by the tail structure of the field-induced first-order phase transition located outside the measurement window.
“In the present case, the increase of C with dropping temperature might be caused by the tail structure of the field-induced first-order phase transition located outside our measurement window.30,43”
From Simultaneous measurement of specific heat and thermal conductivity in pulsed magnetic fields (2023) · cites this paper as [43]
Section 3 (page not available in our copy) discusses magnetization plateaux and a pressure-dependent shift in the temperature of maximum magnetic susceptibility. Searches for heat capacity C, a field-induced first-order transition, and a transition tail outside the measurement window found no passage addressing the proposed explanation. (LLM, conf=0.72)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
