Magnetic characterisation

MFDC Magnetic/ferroelectric/dielectric char.
We provide modular experimental stations to study the evolution of electric and magnetic dipole orders, and their degree of coupling, which is an identifying feature of novel magneto-electric systems. Features for designing multifunctional devices, such as magneto-electric sensors or high-capacity four-state logic memories, can be assessed.
Magnetometry Magnetometry
We provide an automated MagLab-EXA multi-measurement system for nanomaterials characterization. A set of analytical probes (AC/DC magnetometry, magneto-transport, Hall effect etc) is available to indentify technologically useful quantum mechanical phenomena to design materials with optimal device operational capabilities.
MT Magneto-transport
We offer magneto-transport characterizations of semiconductor and metallic samples at temperatures down to liquid He and fields up to 7T. Density and mobility of carriers are measured through Hall effect, as well as quantum transport phenomena in 2D systems at low T. Carrier populations can be tuned by bias voltages and external illumination.
MOKE Magneto-Optic Kerr Effect
By MOKE the magnetic properties (e.g. coercivity, squareness ratio) of single micro-structures can be evaluated: no quantitative measure of the magnetization is provided, but from the shape of the hysteresis loop, both static and dynamic magnetization reversal processes can be investigated in detail.
EPR Electron Paramagnetic Resonance
EPR technique allows the detection and study of transient and stable paramagnetic species such as free radicals, over a very wide range of temperatures.
SQUID Superconducting Quantum Interference Device
SQUID offers high resolving power in deciphering static and dynamic phenomena in low-moment, dilute magnetic systems, by measuring moment versus applied magnetic field or moment versus temperature. It also allows precise determination of the Curie, NĂ©el or blocking temperatures of ferromagnetic, antiferromagnetic or superparamagnetic nanoparticles.
