Rice U. lab grows stable, ultrathin magnets: Rare iron oxide could be combined with 2D materials for electronic, spintronic devices

Rice University researchers have simplified the synthesis of a unique, nearly two-dimensional form of iron oxide with strong magnetic properties that is easy to stack atop other 2D materials.


The material, epsilon iron(III) oxide, shows promise as a building block for exotic nanoscale structures that could be useful for spintronic devices, electronic or storage applications that take advantage of not only the charge of electrons but also their spin states.

Researchers at Rice’s Brown School of Engineering and Wiess School of Natural Sciences reported in the American Chemical Society journal Nano Letters that they had produced oxide flakes through simple chemical vapor deposition. The flakes are easily transferable from their growth substrates and retain their magnetic properties over the long term at room temperature.
