In this study we have fabricated FePtP films by electrodeposition technique. High quality of deposit with low cost is the advantage of this technique. Magnetic thin films are extensively used in various electronic devices including high density recording media and Micro Electro Mechanical System (MEMS) devices. The surface morphology, crystalline structure, grain size and magnetic properties of the plated films prepared at various current densities, bath temperature and concentration of phosphorous source material (NaH2PO2) have been compared. This results shows that the structural & magnetic properties of this thin film depends on the phosphorus content in the film. But the phosphorus content depends on bath temperature and concentration of phosphorous source material (NaH2PO2) . When the bath temperature increases the phosphorus content decreases and hence coercivity increases. Also coercivity increases after annealing. Reasons for variation in magnetic properties and structural characteristics were discussed.

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.
