Fig. 5From: Synthesis and Characteristics of FePt Nanoparticle Films Under In Situ-Applied Magnetic FieldThe hysteresis loops of FePt nanoparticle films for the 2# (a, b) and 3# (c, d) samples. The applied magnetic field during measuring is perpendicular to the film with denotation of H⊥ and parallel to the film with H∥ Back to article page
