Title: Tuning exchange bias by Co doping in Mn₅₀Ni{sub 41–x}Sn₉Co{sub x} melt-spun ribbons

In Mn₅₀Ni{sub 41–x}Sn₉Co{sub x} ribbons, the exchange bias field is very sensitive to the Co content. Based on both theoretical and experimental studies, it has been found that with increasing Co content, the pinned phase (ferromagnetic phase) remains almost unchanged while the pinning phase is changed from a canonical spin glass to a cluster spin glass and finally to a ferromagnetic phase. Changing the Co content in Mn₅₀Ni{sub 41–x}Sn₉Co{sub x} alloys has been proven to be an effective way of tuning the magnetic anisotropy and the phase structure of the pinning phase. With different Co contents, a continuous tuning of the exchange bias field from 345 Oe to 3154 Oe is realized.
