Abstract
The consequences of 85 MeV 16O ion irradiations on the magnetization behavior of micron-sized and nano-sized powders of hexagonal ferrite (SrFe12O19) are examined. The powders were characterized by vibrating sample magnetometery (VSM), Mossbauer spectroscopy and scanning electron microscopy (SEM). Significant changes in hysteresis loop features are observed after irradiation in the case of micron-sized powders, whereas no change is seen in the case of nano-sized powders. The issue of stability of defect states in small systems based on the consideration of elastic energy is discussed.
