Magnetic hysteresis loops of the ZnFe₂O₄ nanowires within AAO measured with the applied field parallel and perpendicular to the axis of the nanowires at (a) 300 K and (b) 80 K by SQUID. The magnified view of the magnetic hysteresis loops is shown in right bottom insets of Fig. 3a and 3b, respectively. RT magnetic hysteresis loops of ZnFe₂ nanowire arrays within AAO templates measured using VSM are shown in left top inset of Fig. 3a
