✦ Synopsis

Neutron powder diffraction experiments were performed for SrV 3 O 7 , which is characterized by the 1/4 depleted V 4ϩ (S 1/2) square lattice model. An antiferromagnetic three-dimensional (3D) long-range order was observed below T N 34.3 K. The 'Stripe Order' spin structure, which is not expected from a classical Heisenberg model, is realized. This spin structure is the same as found in CaV 3 O 7 , but the spin direction here is parallel to the a(stacking)-axis, instead of the c-axis for CaV 3 O 7 .
