DESCRIPTION:Magnetic field sensors have a mature and transversal level of i
 mplementation in the market\, from automotive to biomedical domains. The i
 mpressive technological progress in thin film preparation and characteriza
 tion\, combined with nano-microfabrication tools offer presently large spe
 ctra for device design. The materials discussed include several varieties 
 of thin film materials combined onto multilayer stacks. In addition\, the 
 noise mechanisms (the “killing factor” that limits the MR sensor perfo
 rmance) will be discussed\, and I will show successful strategies for impr
 oving the signal-to-noise ratio\, improving the ultimate field detectable 
 by an MR sensor. Examples where spintronic sensors are useful tools for pr
 ecision sensing will be provided\, including integration with microfluidic
 s\, optical and MEMS micromachined actuators. During my talk\, I will show
  how challenging applications have identified creative solutions\, requiri
 ng joint skills in transversal areas as physics\, materials\, electronics 
 and mechanical engineering.\n\nSpeaker(s): Susana Cardoso de Freitas\, \n\
