THE PRESENT AND FUTURE OF MAGNETIC THIN FILMS

A brief review is given of the magnetic and electric proiperties,magnetoresistant effect and applications of magnetic thin films.After an introduction,the magnetic and electric properties and colossal magnetoresistance effect of rare earth|Mn oxides of the perovskite structure dopped with Ca,Sr and Ba are discussed.Section 3 present the basic concept of interlayer exchange coupling between magnetic layers,giant magnetoresistance effects in multilayered films,and a comparison of the behavior of magnetoresistance effects in spin valve structures,granular films and sandwich films with tunneling effect,and also the development of applications for readout heads.Recent studies and possible results of data storage using near field optics and magnetic nanostructure arrays are discussed in sections 4 and 5,respectively.In section 6 recent investigations on magnetoelectronics are briefly introduced.
