| Abstract | Antiferromagnets (AFMs) with anomalous quantum responses have led to new progress for the under-standing of their magnetic and electronic structures from symmetrical and topological points of view. Two typical topological states are the collinear antiferromagnetic Weyl semimetal (WSM) and Weyl nodal loop semimetal (WNLSM). In comparison with their counterparts in ferromagnets and noncollinear AFMs, WSMs and WNLSMs in collinear AFMs are still awaiting experimental verification. In this paper, we theoretically predict the coexistence of Weyl points (WPs) and Weyl nodal loops (WNLs) in transition metal oxide RuO2. Owing to the small magnetocrystalline anisotropy energy, the WPs and WNLs can transform into each other via tuning the Neel vector. Moreover, since the WPs are very close to the Fermi level and the WNLs are even crossing the Fermi level, the topological states in RuO2 can be easily probed by photoemission and scanning tunneling microscopy methods. Our result provides a promising material platform for the study of WSM and WNLSM states in collinear AFMs. |
