| dc.description | A paramagnetic amorphous Fe<sub>0.33</sub>Zr<sub>0.67</sub> alloy has been studied with Mossbauer spectroscopy and SQUID magnetometry. Low-field magnetization measurements revealed the existence of superparamagnetic nanoparticles of thousands of mu <sub>B</sub> embedded in the alloy with a blocking temperature of 50 K. A saturation of local moments (15.9 mu <sub>B</sub>), possibly clusters of a few Fe ions, is observed at 4.6 K around 10 kOe. The temperature dependence of the high-field magnetic susceptibility of Fe<sub>0.33</sub>Zr<sub>0.67</sub> is interpreted with Curie's law for these Fe clusters and nanoparticles. |
