| Popis: | Hysteresis properties and magnetization processes in exchange coupled Fe 10 Ni 90 /Tb 27 Co 73 bilayers separated by ultrathin Ti spacers of different thicknesses were investigated in temperature range from 79 to 450 K. Magnetization process in most samples with exchange bias took place by magnetization rotation. Exchange bias field decreased monotonously with thickness of Ti spacer increasing while coercivity had a distinguished maximum at critical value of exchange bias disappearance. Exchange bias field was shown to decrease almost linear with temperature increasing until the irreversible fall to zero at blocking temperature, demonstrating very similar behavior for bilayers with ultrathin Ti spacer of different thicknesses. |
