Zero-field cooling (ZFC, solid symbols) and field cooling (FC, empty symbols) of the DC magnetization as a function of temperature from 5 to 140 K for α -Ga_{2− x}Fe_xO₃ with x = 0.1, 0.2, 0.3, and 0.4. A magnetic field of 100 Oe is applied for all the measurements. Arrows denote the definition of the temperatures where irreversible magnetization occurs. Inset is the inverse molar susceptibility as a function of temperature for α -Ga_{2− x}Fe_xO₃ with x = 0.1, 0.2, 0.3, and 0.4. The dash lines are the linear fitting.
