纳米流体铁磁石墨磁化强度的温度振荡
Temperature oscillations of magnetization observed in nanofluid ferromagnetic graphite
摘要：
我们报告了在纳米流体室温铁磁石墨（平均粒径为l=10nm）中观察到的不寻常的磁性。更准确地说，测量的磁化强度表现出低温异常（归因于量子温度以下的有限尺寸效应的表现）以及T= 50 K以上的明显温度振荡（归因于纳米流体中铁磁颗粒之间的硬球型对相关性的表现）。
英文摘要：
We report on unusual magnetic properties observed in the nanofluid room-temperature ferromagnetic graphite (with an average particle size of l=10nm). More precisely, the measured magnetization exhibits a low-temperature anomaly (attributed to manifestation of finite size effects below the quantum temperature) as well as pronounced temperature oscillations above T=50K (attributed to manifestation of the hard-sphere type pair correlations between ferromagnetic particles in the nanofluid).
