Discussion

Experimental findings show single-atom magnets enable efficient information storage, suggesting reduced energy loss and heat generation.

Reading and writing information occurs via mechanical interactions with single-atom magnets, enhancing data density.
Single-atom magnets were used to minimize energy loss during storage by utilizing magnetic exchange force microscopy.
Holmium adatoms on MgO thin films demonstrate significant spin orientation stability under low-heat generation conditions.
These findings highlight a promising future for energy-efficient spintronics at the atomic scale.

Adachi et al. (2025) studied this question.
