Abstract :
LSMO thin films materials have a strong interaction between their electrical and magnetic properties that could be translated into innovative tunable components. The knowledge of the electroactive and magnetoactive properties of these materials is essential for modeling and design of their novel based- devices. The activity of these materials can be described by their electro/magento resistance and magneto capacitance. 400 nm thick LSMO thin film is formed by the chemical solution deposition (CSD). Under electrostatic field, it is assumed that electric current flowing through narrow low resistance path induces intense local magnetic field, resulting in the decrease of film resistance. This letter reports for the tunability of the LSMO resistance versus frequency.
