Giving a look into literature about magnetism, one may ask a question: Which comes first? The new naming of the phenomenon, or the use of an already existing word adapted in order to describe the phenomenon?

Enjoy the paper written by Grazia Biorci from CNR-IRCrES, where she analyses the term “magnetism” in the language and literature and gives some hints on how the linguistic transmission runs along two parallel paths, in balance between the progress of scientific knowledge and the specialization of its language.

This article has been inspired by a collaboration between Grazia Biorci and the OXiNEMS project in the framework of the 20th edition of the Genoa Science Festival for the exhibition “we are all magnetic”, dealing with magnetometers for consumer applications and biomagnetism. The OXiNEMS team acknowledge Grazia for her precious support!

Three talks at conferences by the OXiNEMS members have been done in the last month!

 

On September 8th Nicola Manca gave an oral contribution entitled  "Functional Oxides for Enriched MEMS" at the CMD30-FisMat2023 joint  conference in Milan (IT) about recent advancements in oxide nano-mechanics and the OXiNEMS project.

 

“A Hybrid Superconductor/Nanomechanical Magnetic Field Detector for Biomagnetism” has been presented by Luca Pellegrino at EUCAS23 in Bologna (IT) on September 7th at 10.00 with a contributed talk.

 

 

Luca Pellegrino gave an invited talk at ICCGE20 on August 4th in Napoli (IT) with the title “The role of epitaxy in microelectromechanical systems made with transition metal oxide films”.

The kick-off meeting of LSMOMEMS took place in the GREYC lab at ENSICAEN on 15-16 May 2023. This 2-years project of cooperation IEA 2022 between CNRS-GREYC and CNR-SPIN aims developing oxide-based MEMS resonators for infrared detection. The project is coordinated by Dr. Laurence Méchin (CNRS-GREYC, Caen) and Dr. Nicola Manca (CNR-SPIN, Genova).

The objective of LSMOMEMS is to study the principle of operation of infrared bolometers making use of MEMS resonators (i.e. MEMS bolometers) fabricated with epitaxial oxide thin films. The long-term goal of LSMOMEMS is to demonstrate the potential of bolometers made of (La,Sr)MnO3 in relevant technological applications, such as Non Dispersive InfraRed (NDIR) gas sensors, IR spectroscopic sensing or imaging devices.
This project will further develop the technology of complex oxides micromechanics by combining the expertise on micro-fabrication and thermo-mechanical characterization of the two research units. LSMOMEMS will work on two research directions: the development of full-oxide MEMS systems made from epitaxial oxide heterostructures and the integration of complex oxides with silicon MEMS technology. Exchange activities of researchers and students will allow developing a shared framework for performance analysis and fabrication protocols. LSMO-based MEMS are currently under development within the OXiNEMS project.
Nicola Manca had also the opportunity to present the OXiNEMS project to CNRS-GREYC members.
