Abstract :
Mn-Zn ferrite thin films with coercive force of approximately 4 kA/m were obtained by a low-temperature process using laser-ablation technique. Thin films were prepared at substrate temperature of room temperature in Ar atmosphere with a shadow mask using glass substrates. It was found that the spinel structure is formed in the films and that the surface roughness caused by large particles is improved
