| The aim of the « Magnetic Nanomaterials »(nMatMag)
activity is to correlate the magnetic and transport behavior of
magnetic nanomaterials and nanodevices to their structure and synthesis
process in order to be able to tune and optimize their properties.
We then part of our work concerns the development of new local methods
for measuring the magnetic and structural properties at the
|
nanometer scale
and other is about the progress of new method in synthesis.
The systems we study present strong technological interests, in
particular in the field of spintronics and magnetic recording. The
applications in the field of life sciences, with the development
of nanomaterials for therapeutic application form also part of our
concerns.

Through techniques of elaboration,
mainly “sputtering”
for thin films, and of characterization of devices, our aim is to
understand how the modifications, at the nanometer scale of the
atomic and electronic structure, of these systems modify their magnetic
and magnetotransport behaviors.
The structural characterizations are carried out by TEM, diffraction
and reflectivity of x-rays (for the systems in thin and multi-layer
layers), WAXS and SAXS (for the nano-objects) and AFM.
We perform magnetic measurements by using the traditional experimental
means of which we lay out:
- Measurements of cycle
of magnetization by
Kerr effect
- Magnetization measurements
by VSM
- MFM
