$\beta$-TeVO$_4$ is a frustrated spin 1/2 zig-zag chain system,where spin-density-wave (SDW), vector chiral (VC)and an exotic dynamic spin-stripe phase compete at low temperatures. Here we use torque magnetometry to study the anisotropy of these phases in magnetic fields of up to 5 T. Our results show that the magnetic-field-induced spin reorientation occurs in the SDW and in the spin stripe phases for $\mu_0 H \geq 2$~T. The observed spin reorientation is a new element of the anisotropic phase…

Spin-stripe phase in a frustrated zigzag spin-1/2 chain

It is shown that spin-stripe textures may develop also in antiferromagnets, where long-range dipole–dipole magnetic interactions are absent and this concept provides an alternative route for the stripe formation in strongly correlated electron systems and may help understanding of other widespread, yet still elusive, stripe-related phenomena.
