AB - The 11 series of the iron chalcogenide has the simplest structure among all the iron-based superconductors, yet rather rich physical properties. In this way, the study on the 11 series has been one of the hottest topics in the iron-based superconductors. In this research, we have successfully synthesized Fe1-xNixS (x = 0, 0.01, 0.05, 0.1, 0.2) single crystals with P4/nmm using a hydrothermal method and self-flux method, and then studied their magnetic properties. Ni doping on FeS superconductor would suddenly suppress superconductivity. Meanwhile, it introduces a short-range antiferromagnetism and weak ferromagnetism, the coexistence of which induces an exchange bias. Our study further proves that superconductivity in 11 series is rather sensitive to the impurity on the Fe site, which is close to the short-range antiferromagnetism. Besides, their exchange bias would have potential application on information storage, spin valves, magnetic tunnel junction, etc.
