Data for Composite superconducting orders and magnetism in CeRh2As2

Abstract

This archive contains the data plotted in the paper F. Jakubczyk, J. M. Link, C. Timm, Composite superconducting orders and magnetism in CeRh2As2, Phys. Rev. Res. (2026). For this paper, the interplay of the ordered phases in CeRh2As2 was investigated within a theoretical framework based on symmetry analysis combined with Bogoliubov--de Gennes and Landau methods. This approach accurately reproduces current experimental results for varying temperature as well as out-of-plane and in-plane magnetic field, both if the transition to a magnetic phase occurs below the superconducting critical temperature and if it occurs above. Calculations and plots of phase diagrams, free energy, order-parameter amplitudes and thermodynamic observables were carried out using Mathematica.
