Utilização de fita orgânica de ZrO2 como substrato flexível para filmes ferromagnéticos. 51 f.

The study of magnetic films plays a key role in the development of these devices, which makes essential the search for new films compositions. In this work, we investigate the structural, magnetic and electric properties of films composed by two layers of $Ni_{81}Fe_{19}$ intermediated by a layer of $Cr$ deposited on flexible $ZrO_2$ green tape and compared with the properties presented by films of the same configuration of layers deposited on glass. The structural characterization of films on $ZrO_2$ points to the growth of the $Ni_{81}Fe_{19}$ in the crystallographic direction [111], as well as in the films on glass. The magnetic characterization of films $ZrO_2$ points to the dependence of the magnetic properties with the $Ni_{81}Fe_{19}$ thickness, again replicating the results of the films on glass. Lastly, electrical characterization points out that films on $ZrO_2$ feature conductive behaviour similar to the films on glass. Based on these results, we identify the mirroring between the properties of films on $ZrO_2$ and films on glass, which opens a range of new applications for use of $ZrO_2$ in the development of storage, reading, and data processing devices.openAccessFilmes magnéticosFita orgânica de ZrO2Espelhamento de propriedadesbachelorThesisCNPQ::CIENCIAS EXATAS E DA TERRA::FISICA
