Emergence of nontrivial low-energy Dirac fermions in antiferromagnetic EuCd2As2

When magnetism meets topology, colorful novel states can be created in materials. The realization of magnetic topological Dirac materials remains a major issue in topological physics studies. In this work, it is ascertained that the topologically nontrivial ground state of EuCd2As2 is a good candidate for different types of magnetic topological state: magnetic topological Dirac semimetal, axion insulator, antiferromagnetic TCI, and higher order topological insulator. This documents include all the raw data in the reference Advanced Materials 32, 1907565 (2020). This files contains all the raw data that published in the related paper. Fig.1.zip includes dat format transport measurement results which can be open by Origin. Fig.2.zip contains ibw format ARPES spectra which can be opened by IGOR. Fig.3.zip contains figures of the calculated FS, band structure. The dat format files can be open by IGOR. Fig.4.zip contains both ARPES spectra and STS data. sxm format file can be opened by SXM software which is commonly used for STM/STS data. The h5 format file can be opened by IGOR. H5 format is also commonly used for high dimensional data in ARPES experiments. Fig.5 is mainly the calculated band structure of the related fig.5. The itx format can be opened by IGOR. All the ibw format files are duplicated in the txt file with same name. The SXM file is also duplicated in txt file with same name.
