    This archive contains the data of primarily experimental origin that are plotted in the main and supplementary figures of the article "Exposing the odd-parity superconductivity in CeRh2As2 with hydrostatic pressure" by M. Pfeiffer et al., published in Physical Review B 110, L100504 (2024). The data are provided it the form of text files, and the file names indicate where the data appear in the publication. These files contain tab-separated columns of numerical values. The first row of each file reads the column names. Rounding errors may give rise to some negligible inconsistencies between the data in this archive and the article. The figure data that come from other publications are not provided here. When more than one figure contain the same set of data, it is generally only provided once, in the folder corresponding to the first figure in which that set of data appears. Additional data and details related to the article can be obtained upon a reasonable request from the following authors: Konstantin Semeniuk (konstantin.semeniuk@cpfs.mpg.de), Elena Hassinger (elena.hassinger@tu-dresden.de).

    Data Underpinning: Magnetic phase diagram of rouaite, Cu₂⁢(OH)₃⁢NO₃

    This contains the data underpinning our recent paper on rouaite, Cu₂⁢(OH)₃⁢NO₃, published in Phys. Rev. B 110, 054442 (2024). The abstract of the article is reproduced below: Spinon-magnon mixing was recently reported in botallackite Cu2⁢(OH)3⁢Br with a uniaxially compressed triangular lattice of Cu2+ quantum spins [H. Zhang et al., Phys. Rev. Lett. 125, 037204 (2020)]. Its nitrate counterpart rouaite, Cu2⁢(OH)3⁢NO3, has a highly analogous structure and might be expected to exhibit similar physics. To lay a foundation for research on this material, we clarify rouaite's magnetic phase diagram and identify both low-field phases. The low-temperature magnetic state consists of alternating ferromagnetic and antiferromagnetic chains, as in botallackite, but with additional canting, leading to net moments on all chains which rotate from one chain to another to form a 90∘ cycloidal pattern. The higher-temperature phase is a helical modulation of this order, wherein the spins rotate from one Cu plane to the next. This extends to zero temperature for fields perpendicular to the chains, leading to a set of low-temperature field-induced phase transitions. Rouaite may offer another platform for spinon-magnon mixing, while our results suggest a delicate balance of interactions and high tunability of the magnetism.
