Intensive investigations on nanoscale magnetism have promoted
remarkable
progressintechnologicalapplicationsofmagnetisminvariousareas.Thete-
nical progress of recent years in the preparations of multilayer
thin ?lms and nanowires led to the discovery of Giant
Magnetoresistance (GMR), imp- ing an extraordinary change in the
resistivity of the material by varying the applied external
magnetic ?eld. The Nobel Prize for Physics in 2007 was
awardedtoAlbertFertandPeterGrun ] bergfortheirdiscoveryofGMR.App-
cations of this phenomenon have revolutionizedtechniques for
retrieving data

sors as well as the development of a new generation of electronics.
The use of
GMRcanberegardedasoneofthe?rstmajorapplicationsofnanotechnology.
The GMR materials have already found applications as sensors of low
magnetic ?eld, a key component of computer hard disk heads,
magnetores- tive RAM chips etc. The "read" heads for magnetic hard
disk drives have allowed us to increase the storage density on a
disk drive from 1 to 20 Gbit per square inch, merely by the
incorporation of the new GMR materials. On the other hand, recently
discovered giant magneto-impedance (GMI) mate- als look very
promising in the development of a new generation of microwave band
electronic devices (such as switches, attenuators, and antennas)
which could be managed electrically."
