The hysteresis loops of diluted antiferromagnetic (DAF) thin films are studied by means of Monte Carlo simulations. The major hysteresis loops exhibit rich variety of shapes. A diagram of shape is demonstrated. Loop shift and coercivity enhancement are observed exclusively in field-cooling minor loops, which indicates that the effects are not the intrinsic properties of the DAF thin films. The numerical results may help to understand the stable mechanism of the uncompensated spins in the DAF layer and exchange bias systems.
