研究了电子束蒸发的（Ni 83 Fe 17/Cu）10和（Ni 66 Fe 16 Co 18/Cu）10多层膜的磁性和输运性质随Cu间隔层、磁性层和Ta缓冲层厚度以及退火条件的变化。所有多层膜在沉积状态下都表现出非常小的巨磁电阻（GMR）效应（<0.3%），然而，在300-325 °C的磁性后退火后，GMR增加到4.5%-7%，这取决于多层膜类型。与溅射的Ni-Fe-（Co）/Cu多层膜相反，GMR没有表现出作为Cu厚度的函数的振荡行为。与溅射“不连续"Ni-Fe/Ag多层膜中报道的类似，据信Cu沿沿着Ni-Fe-（Co）晶界扩散在Ni-Fe-（Co）层中产生层内磁不连续性，这促进了层间反铁磁耦合。蒸发的Ni-Fe/Cu多层膜具有非常低的剩磁，非常低的磁滞，并且在多层膜的厚度上具有非常均匀的GMR特性。
The magnetic and transport properties of electron‐beam evaporated (Ni83Fe17/Cu)10 and (Ni66Fe16Co18/Cu)10 multilayers were studied as a function of the Cu spacer, magnetic layer and Ta buffer layer thicknesses, as well as annealing conditions. All multilayers exhibited very small giant magnetoresistance (GMR) effect (<0.3%) in the as‐deposited state, however, after magnetic post‐annealing at 300–325 °C, GMR increased up to 4.5%–7%, depending on the multilayer type. In contrast to sputtered Ni‐Fe‐(Co)/Cu multilayers, GMR showed no oscillatory behavior as a function of Cu thickness. Similar to that reported in sputtered ‘‘discontinuous’’ Ni‐Fe/Ag multilayers, it is believed that Cu diffusion along the Ni‐Fe‐(Co) grain boundaries creates intra‐layer magnetic discontinuities in Ni‐Fe‐(Co) layers which promote inter‐layer antiferromagnetic coupling. The evaporated Ni‐Fe/Cu multilayers exhibited very low remanence, exceptionally low hysteresis, and quite uniform GMR properties through the thickness of the multi...
