This research topic focuses on the development and study of:
Such studies use many techniques mastered within IRAMIS: thin film growth (in particular oxides), magnetic transport measurements, (polarized) neutron scattering, ... The characterization of magnetic sensors is performed in a "ultra low magnetic noise laboratory" necessary to the development of multiple applications: non-destructive testing, security, speed sensors, current sensors ....
The "Nanomagnetism and Oxides Laboratory" (LNO) within SPEC has its activity fully focused on this topic.
Multiferroic materials are multifunctional materials having simultaneously several "ferroic" properties: ferromagnetism, ferroelectricity and / or ferro-elasticity. Their development in thin layers allows to design functional devices, where their coupled properties can be used.

Measurement of the cardiac electrical activity allows following the heart dynamics. Usually measured with electrodes during an electrocardiogram (ECG), this activity can also be studied by monitoring the magnetic component, induced by the circulation of the heart electric currents. This is ... More »
Making still smaller and less power consuming digital memories for mobile electronics? Scientists from CNRS and University Paris Sud XI (Laboratory of Solid State Physics, CNRS / Univ. Paris-Sud 11 and Institut Néel) and CEA-IRAMIS come to demonstrate the feasibility, thanks to ... More »
Delphine Lebeugle, Dorothée Colson, Anne Forget, Michel Viret (IRAMIS/SPEC CEA-Saclay) Arsen Goukassov, Alexandre Bataille (IRAMIS/LLB CEA-Saclay) Magnetic materials are heavily used in the dynamic storage of information (hard disk drive, head for reading). For these applications, they are ... More »
