Abstract

We modify an antiferromagnetic-based helimagnet Ni2InSbO6 to a ferrimagnetic-based helimagnet by partial substitution of Cr for In. Upon applying a magnetic field, uncompensated moments bring about the collinear ferrimagnetic structure featured by the plateaulike magnetization and the disappearance of the magnetic superstructure. Furthermore, we have found an incommensurate magnetic phase distinct from the zero-field helix phase just below the Néel temperature as magnetic skyrmion crystal phases in some other noncentrosymmetric magnets. These findings provide a methodology to design non-coplanar magnetic states based on the material database.
