摘要

磁力顯微鏡 (MFM) 技術已被用於研究 Ni/SiO2 納米薄膜和植物葉片衍生的石墨烯量子點簇的磁行為。已經通過 MFM 和低溫電子傳輸測量系統研究了厚度為 150 nm 和 300 nm 的鎳納米薄膜，揭示了其強磁響應。在室溫下，磁化水平隨薄膜厚度和疇尺寸的增加而增加，這對於非揮發性記憶體設備可能具有重要意義。植物衍生的 GQDCs 報告說，磁響應隨簇的寬度和高度而變化，而較小的則沒有顯示任何磁響應。在室溫下觀察到的磁場可能會導致碳基存儲介質設備的潛在應用。

Magnetic Force Microscopy (MFM) technique has been used to study the magnetic behaviour of Ni/SiO2 nanofilms and plant leaf-derived graphene quantum dot clusters. Nickel nanofilms of thicknesses 150 nm and 300 nm have been studied via MFM and low temperature electronic transport measurement system which revealed its strong magnetic response. The magnetization level increased with film thickness and domain size has been observed to increase with thickness at room temperature which could be of great significance for non-volatile memory storage devices. The plant derived GQDCs reported that the magnetic response varied with width and height of the clusters while the smaller ones did not show any magnetic response. The magnetic field was observed at room temperature could lead to potential applications for carbon-based storage media devices.
