Abstract :
Exchange bias (EB) effects in Y Fe0.5Cr0.5O3, which exhibits magnetization reversal, were systemically investigated. Above the compensation temperature ( T comp ), only negative EB field appears, whereas the sign of the EB field below T comp can be reversed from positive to negative by applying a large cooling field. The difference between the EB behaviors above and below T comp , which are strictly related to magnetization reversal, may originate from the competing magnetic anisotropy of the system. The sign reversal of both magnetization and EB field coexisting in a single system can be tuned in a preselected and convenient way.
