We report fabrication of EuSb2 single-crystalline films and investigation of their quantum transport. First-principles calculations demonstrate that EuSb2 is a magnetic topological nodal-line semimetal protected by nonsymmorphic symmetry. Observed Shubnikov-de Haas oscillations with multiple frequency components exhibit small effective masses and two-dimensional field-angle dependence even in a 250 nm thick film, further suggesting possible contributions of surface states. This finding of the high-mobility magnetic topological semimetal will trigger further investigation of exotic quantum transport phenomena by controlling magnetic order in topological semimetal films.
