英文摘要	We report low-temperature heat transport measurements on superconducting iron sulfide FeS with T-c approximate to 5 K, which has the same crystal structure and similar electronic band structure to the superconducting iron selenide FeSe. In zero magnetic field, a significant residual linear term kappa(0)/T is observed. At low field, kappa(0)/T increases rapidly with increasing field. These results suggest a nodal superconducting gap in FeS. We compare it with the sister compound FeSe and other iron-based superconductors with nodal gaps.; Ministry of Science and Technology of China [2012CB821402, 2015CB921401, 2016YFA0300503]; Natural Science Foundation of China; Program for Professor of Special Appointment (Eastern Scholar) at Shanghai Institutions of Higher Learning; STCSM of China [15XD1500200]; Strategic Priority Research Program (B) of the Chinese Academy of Sciences [XDB04040200]; SCI(E); ARTICLE; huangfq@mail.sic.ac.cn; shiyan_li@fudan.edu.cn; 10; 94
