Angular dependence of exchange anisotropy on the cooling field in ferromagnet/fluoride thin films
Angular dependence of exchange anisotropy on the cooling field in ferromagnet/fluoride thin films
Exchange anisotropy in ferromagnet/antiferromagnet (FM/AF) films is usually introduced along the cooling field or FM magnetization direction. Here we investigate the dependence of the exchange anisotropy, loop bifurcation, and reversal mechanism on the cooling field direction using vector magnetometry. Three types of samples ($\mathrm{FM}=\mathrm{Fe}$, $\mathrm{Ni}∕\mathrm{AF}=\mathrm{Fe}{\mathrm{F}}_{2}$, $\mathrm{Mn}{\mathrm{F}}_{2}$) have been studied where …
