title = "Thermally driven commensurate-incommensurate transition tracked by magnetochromism in chiral polar Ni2In0.9Cr0.1SbO6",
abstract = "Ni2In0.9Cr0.1SbO6 is a trigonal chiral polar helimagnet with multiferroic nature. Here, we perform optical absorption measurements on Ni2In0.9Cr0.1SbO6 in magnetic fields. The observed magnetochromism is attributed to the spin-dependent transition probability of the intra-atomic d-d excitation from the 3A2g ground state to the 1Eg excited state of Ni2+ ions with the 3d8 electronic configuration. Exploiting the magnetodielectric coupling in optical frequencies, we propose that the boundary between ferrimagnetic and incommensurate magnetic phases of Ni2In0.9Cr0.1SbO6 in 6 T along the c axis should lie at around 50 K.",
