Fig. 2: Tb thickness dependence of magnetization and anisotropy.

a Magnetization of the [Pt (3 nm)/Co (\(1.3\) nm)/Tb (\({t}_{{{{\rm{Tb}}}}}\))/Al (3 nm)]×5 multilayers as a function of the Tb thickness. The black dotted line represents the magnetization of Pt|Co|Al based multilayers in the absence of any Tb. The blue and red dotted lines are guide to eye for the variation of magnetization and anisotropy, respectively. The error bars associated to each data point corresponds to the uncertainty of the measurements. Phase signals at demagnetized state measured using conventional MFM for (b: \({t}_{{{{\rm{Tb}}}}}=0.25\) nm, c: \({t}_{{{{\rm{Tb}}}}}=0.75\) nm, d: \({t}_{{{{\rm{Tb}}}}}=1.0\) nm). The color scale bar for all the images is 0.5°.
