Hot off the press: New Paper in Journal of Magnetism and Magnetic Materials!
The article “Magnetoelastic coupling behaviour of nanocrystalline ε-Fe2O3” was published in Journal of Magnetism and Magnetic Materials!
Tag: epsilon phase
Hot off the press: Ma and Martí’s work published in JMMM!
Members on N&N Group have published yet another article in recent days. The paper “Magnetic properties of Cr-substituted ε-(Fe1-xCrx)2O3 nanoparticles with epsilon structure” authored by Ma Zheng and Martí Gich was published in the Journal of Magnetism and Magnetic Materials.
Hot off the press: paper in Advanced Electronic Materials!
A paper authored by Martí Gich, “Unconventional Ferroelectric Switching via Local Domain Wall Motion in Multiferroic ε‐Fe2O3 Films“, was recently published in open access in Advanced Electronic Materials. It is a result of a collaboration between scientists from ICMAB, Aalto University and Forschungszentrum Jülich. It has received funding from the ERC.
Congratulations Martí!
Zheng Ma gave a talk at Joint European Magnetic Symposia (JEMS2019)
Zheng Ma, PhD candidate at the N&N Group, attended Joint European Magnetic Symposia (JEMS2019) in Uppsala, Sweden (26-30 August). He gave a talk “Structural and Magnetic Properties of Cr-substituted ε-Fe2O3 Nanoparticles”. It was a collaborative work between our group (supervised by Martí Gich) and CMEOS group in ICMAB, as well as our colleagues from ALBA synchrotron.
Good job Ma!
Hot off the press: Published paper in Nature Communications!
We are happy to announce that last 1st of November 2018, the paper “Stability and nature of the volume collapse of ε-Fe2O3 under extreme conditions” was published on the journal Nature Communications. This study is co-authored by the permanent researcher at the N&N group Martí Gich.
Abstract: Iron oxides are among the major constituents of the deep Earth’s interior. Among them, the epsilon phase of Fe2O3 is one of the less studied polymorphs and there is a lack of information about its structural, electronic and magnetic transformations at extreme conditions. Here we report the precise determination of its equation of state and a deep analysis of the evolution of the polyhedral units under compression, thanks to the agreement between our experiments and ab-initio simulations. Our results indicate that this material, with remarkable magnetic properties, is stable at pressures up to 27 GPa. Above 27 GPa, a volume collapse has been observed and ascribed to a change of the local environment of the tetrahedrally coordinated iron towards an octahedral coordination, finding evidence for a different iron oxide polymorph.
