英文摘要	We report on the strain-induced switch between ferromagnetic (FM) and antiferromagnetic (AFM) orderings in 1T-CrX2 (X = Se, Te) monolayers based on first-principles calculations. The CrSe2 and CrTe2 monolayers without strains are found to be AFM and FM, respectively. Under biaxial tensile strain, the CrSe2 monolayer tends to be FM when the strain is larger than 2%. The FM state is further stabilized when the strain is increased. Moreover, the CrSe2 monolayer becomes half metallic when the tensile strain is larger than 10%, while for the CrTe2 monolayer, the critical strain at which the transition between the FM and AFM states occurs is compressive, of -1%. Relatively small tensile strains of 4% and 2%, respectively, can enhance the Curie temperature of the CrSe2 and CrTe2 monolayers above room temperature. The strain-induced switch between the FM and AFM states in a CrSe2 (CrTe2) monolayer can be understood by the competition between the AFM Cr-Cr direct exchange interaction and the FM Cr-Se(Te)-Cr superexchange interaction. Tunable and attractive magnetic and electronic properties controlled by flexible strain are desirable for future nanoelectronic applications.
