Hard magnetic thin films of Alnico alloy having different thickness were deposited on a ceramic substrate by dc sputtering. The target was made of commercial Alnico permanent magnet having nominal composition Fe49Co23Al11Ni14Cu3. The amorphicity of as-deposited films has been checked by X-ray diffraction technique. Selected samples have been submitted to a controlled annealing to induce the amorphous-to-crystalline transformation. The influence of thermal treatments on the hysteresis properties has been studied as a function of thickness and microstructure on annealed samples..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
