Researchers discover ferromagnetism induced by defects in correlated 2D materials

A weak ferromagnetic (FM) ground state at low temperature in few-layered van der Waals (vdW) magnetic Ni1-xCoxPS3 nanosheets containing sulfur vacancies (Sv) was discovered by a research team led by Prof. He Jun from National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Jin Song from the University of Wisconsin-Madison. This work was published in Science Advances.
