Temperature dependencies of magnetization and electrical resistivity for the bulk polycrystalline Tb sample. An applied magnetic field is equal to 100 Oe.
VSM hysteresis loops measured at different temperatures for the bulk polycrystalline Tb sample.
MR curves measured at different temperatures for the bulk polycrystalline Tb sample. Left column—measurements in the longitudinal configuration, right column—measurements in the transverse configuration.
Field dependence of the resistivity at 250 K at low fields measured in the longitudinal configuration for the bulk Tb sample. The solid line is the fit according to Eq. (1) using the experimental magnetization data plotted in Fig. 2.
MR curves for and multilayers with different measured in the longitudinal (◼,▲) and transverse (◻, △) configurations. The data corresponding to the points (◼,◻) were measured at . For data corresponding to the points (▲, △) the temperatures are shown near the curves. The magnetic ordering temperature is also shown for each multilayered structure.
curves measured at for the (a), (b), and the (c) multilayers.
HRTEM bright field image (a) and energy-filtered TEM image of Tb, where the bright areas indicate the presence of Tb (b) for the sample.
Normalized MR (open symbols) measured in the longitudinal configuration and magnetization square (full symbols) as a function of magnetic field for the (a) and (b) samples. is a proportionality constant.
curves measured at 5 and 50 K for the sample.
