Abstract

The formation of soft magnets on paper(SMOP) is proposed for the first time and we have demonstrated it successfully. Iorn was used to form the soft magnet thin film on paper. And Cr layer was used as a buffer layer because the roughness of substrate(paper) is not negligible. The maximum magnetization of Cr/Fe/Cr/Paper(Fe:5000${\AA}$) is about 1000 [emu/cc] and the coercive field is about 80 [Oe.]. It is necessary to reduce the coercivity and to enlarge the magnetization value of SMOP to perform a good soft magnetic characteristics on paper. On, the permalloy material is the proper candidate for its high permeability, low coercivity and high magnetization values.
