Abstract
The magnetization and neutron scattering studies of a S = 1/2 two-dimensional (2D) square lattice antiferromagnet (K2V3O8) were studied. A phase transition with an antiferromagnetic ordered state accompanied by weak ferromagnetism was observed. A conventional spin-flop phase transition with field applied along the c axis and a unique spin reorientation in the presence of a basal plane magnetic field were found.
