(a) SAR values for 6 and 8 μm Co₃₅Fe₆₅ nanowires in glycerol at various concentrations, with the nanowires randomly oriented or aligned parallel to the AMF. (b) Heating curves for 8 μm Co₃₅Fe₆₅ nanowires (5 mg/ml) in VS55 at 360 kHz and 20 or 25 kA/m. (c) Heating curves for 8 μm Co₃₅Fe₆₅ nanowires at 1, 2.5, or 5 mg Co₃₅Fe₆₅/ml at 25 or 30 kA/m with the nanowires randomly oriented or aligned parallel to the AMF. (d) Minor hysteresis loops of 8 μm Co₃₅Fe₆₅ nanowires aligned in an AAO membrane parallel to the applied field. Minor loops with nanowires perpendicular to the applied field are in ESE (Fig S5d). Repeated colors in (b) and (c) are repeated measurements.
