Short abstract:
At the microscopic scale, magnetic materials exhibit properties that may differ from those observed at macroscopic sizes, opening the field to a new type of electronics called spin electronics. Where classical electronics uses the charge of the electron, spin electronics offers an additional degree of freedom by also manipulating the electron's magnetic moment, the spin. Demonstrated experimentally in 1988 independently by Albert Fert and Peter Grünberg, winners of the 2007 Nobel Prize in Physics for this discovery, spin electronics is now widely used in computer hard disks as read heads, magnetic memories but also for new types of sensors, such as in the field of cell phones or automobiles.
They also offer new possibilities for probing the properties of living organisms. It is thus possible to detect cells in very small volumes, or to measure cardiac, muscular or neuronal rhythms at different scales of the structures studied.
In this talk, I will show how to develop devices based on spin electronics for recording biological signals..
