Magnetic-field induced long-range antiferromagnetic order in two-dimensional frustrated spin-1/2 systems
Mikheenkov A. V. , Nagaev E. L. , Zhasinas E. V.
It is generally believed that in frustrated two-dimensional spin-1/2 antiferromagnets the long-range antiferromagnetic order may be absent because of quantum spin fluctuations. A relatively weak magnetic field may induce the canted antiferromagnetic ordering instead of the usual one-sublattice magnetic ordering. © 1995 American Institute of Physics.
