Abstract

Magnetic thin films are very interesting materials for applications in electronics, sensors and other fields where miniaturisation is a key issue. The great variety of compositions, structures and magnetic features makes it difficult to provide a single method of preparation for all of them. Pulsed laser deposition (PLD) has many advantages in this sense. It can be used for oxides and metals, epitaxial growth and amorphous film preparation, and a great number of parameters can be independently controlled during deposition. In this work we summarise recent research on magnetic thin films obtained by PLD, including METGLASS like amorphous films for magnetoelastic or Giant Magneto-impedance applications, nano granular Co-Cu and Fe-Ag alloys with Giant Magneto-resistance and mixed oxides with perovskite structure and Colossal Magneto-resistance. The preparation conditions and magnetic and magneto-transport properties are discussed..
