Changing the Fe concentration in the (Ga,Sc,Fe)₂O₃ spin glass

We report the characterization of (GaSc)_2-xFe_xO₃. The composition range where the multinary metal oxide is stable, as well as nonlinear trends in the lattice parameters are described. Select compositions of GaSc_1-yFe_yO₃ are included to compare trends. Fe shows an enhanced solubility when replacing Sc rather than Ga. Field- and temperature-dependent magnetic data are included, and linear trends in the magnetic frustration are discussed alongside a brief comparison to the magnetic properties of GaSc_1-yFe_yO₃. The field-dependent properties, as well as anomalies in the hysteresis loops and relaxation of the remnant magnetization are discussed, as well as indications that long-range order may be present in dilute Fe samples.
