Magnetic-field-induced long-range antiferromagnetic order in two-dimensional frustrated spin-1/2 systems
Mikheenkov A.V., Nagaev E.L., Zhasinas E.V.
One generally believes that in frustrated 2D spin-1/2 antiferromagnets the long-range antiferromagnetic order may be absent due to the quantum spin fluctuations. A relatively weak magnetic field may induce the canted antiferromagnetic ordering instead of the usuall one sublattice magnetic ordering.
