Electrochemically deposited cobalt/platinum (Co/Pt) film into porous silicon: Structural investigation and magnetic properties

► Porous silicon (PSi) with pore sizes between 5 and 100 nm was fabricated. ► Co/Pt magnetic film was electrochemically deposited into PSi template. ► Thermal annealing led to the crystallization of the films in the L10 ordered phase. ► The coercivity and magnetization were significantly enhanced. ► The current approach is beneficial for current and future PSi-based technologies.
