Figure 5From: Controlling exchange bias in Fe3O4/FeO composite particles prepared by pulsed laser irradiation Illustration of the FC and ZFC hysteresis loops. (a) Hysteresis loops of the Fe3O4/FeO particles fabricated at 177 mJ/pulse.cm2. FC means that the sample is cooled from 300 to 5 K in the 50 kOe field. (b) The magnification around origin of hysteresis loops of the Fe3O4/FeO particles fabricated at 177 mJ/pulse cm2.Back to article page
