AI总结:

本研究针对未掺杂Cu-Cu2O-rGO纳米复合材料的室温铁磁与低温顺磁现象,基于3D Ising模型用唯象方法解释其源于界面处Cu空位产生的任意自旋。

摘要:

本研究证实未掺杂的Cu-Cu2O-rGO纳米复合材料中存在室温铁磁性,同时低温下呈现顺磁性。研究采用唯象方法,基于3D Ising模型解释该现象,该模型对应Cu2O体系中优先在界面处的Cu空位产生的任意自旋。

英文摘要:

The observation of room temperature ferromagnetism along with a low temperature paramagnetic counterpart in undoped Cu-Cu2O-rGO nanocomposite was demonstrated. A phenomenological approach was taken to explain the observations based on 3D Ising model for arbitrary spins generated due to Cu vacancy in the Cu2O system preferably at the interface.
