| contents | Ferrimagnets have the potential to play a key role in spintronics due to their high stability, low energy consumption, and rapid magnetic state switching. These characteristics are typically observed in ferrimagnetic materials near magnetic or angular compensation states. Near the magnetic compensation point, an external field can disrupt the collinearity between the sublattices, leading to aligned magnetic projections. In this work, a violation of antiferromagnetic ordering is detected by a change in the direction of the effective field induced by spin-orbit torque, without altering the dominance type. In the studied W-Co70Tb30-Ru structure, the canted phase region is observed near room temperature under external fields of approximately 0.1 T. Using macrospin simulations and analytical derivations, a correlation is established between anisotropy, interlattice exchange interaction, and the presence of the canted phase region. |
