The research aims to investigate how reduced graphene oxide hydrogel can suppress the transformation of maghemite to hematite under specific environmental conditions.
Conducted experiments under high temperature and humidity conditions.
Used reduced graphene oxide hydrogel as an intervention material.
Monitored the transformation of γ-Fe2O3 to α-Fe2O3.
Reduction in the rate of transformation from maghemite to hematite was observed.
The presence of graphene oxide hydrogel significantly stabilized maghemite.
Enhanced magnetic properties were noted in treated samples compared to untreated ones.
Abstract
Maghemite (γ-Fe2O3) is an important magnetic material for wide utilization, however, it tends to transform into hematite (α-Fe2O3) under high temperature and humidity (HT & H). Here, we report that...
