Open call for JAE Intro 2020: three projects offered by N&N Group

The CSIC launched the JAE Intro 2020: Introduction to research fellowships for University students. The objective of this program is to introduce students to research activity in diverse scientific areas and to enable them to be in contact with CSIC research centres. Three projects are offered by N&N Group. The call is open from 9 March to 9 April 2020.

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!

Hot off the press: new paper in ACS Applied Materials & Interfaces!

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! 

Hurray! Martí Gich awarded with a 2018 ERC Consolidator Grant

We are very excited to announce that the N&N researcher Martí Gich, has been awarded with a European Research Council (ERC) Consolidator Grant (CoG) for his project entitled “Ferrites-by-design for Millimeter-wave and Terahertz Technologies” (FeMiT). Martí Gich will carry out his project in the period 2019-2024 with a total of nearly 2 M€ to cover the project costs.

 

All the N&N members are very enthusiastic about the project and wish Marti a lot of success, congratulations!

 

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. DOI: https://doi.org/10.1038/s41467-018-06966-9
