Abstract

Magnetic response properties of silicene, germanene, and stanene rings have been explored. The total magnetic moment of the rings can be modulated by the exchange field. The magnetic moment of the rings can be regulated and keeps the constant valuewithin certain ferromagnetic exchange filed window. Diamagnetism–paramagnetism or paramagnetism–diamagnetism transitions are observed with the increase of antiferromagnetic exchange field.
