Abstract
The magnetic properties of borophene structure are studied for the first time by the effective-field theory with correlations. This method has been successfully used in analyzing the magnetic mechanism of graphene. The borophene consisting of 36 boron atoms with a central hexagonal vacancy can be described by Ising model. The general formula of the magnetization for the borophene is given. Possible physical mechanism of the emergence magnetic properties is demonstrated. The effects of the exchange coupling and the anisotropy of the magnetization, the susceptibility the blocking temperature and hysteresis loops of borophene are discussed. We also illustrate the possibility to test the predicted magnetism in an experiment, such as the maximum on the magnetization curve. Our study may provide an opportunity for the design of a new type of memory-switching or sensors by using earth-rich nonmagnetic boron materials.
