论文摘要
我们报告了自组装核心/壳/壳fe $ _3 $ o $ $ _4 $/co $ _ {1-x} $ zn $ _x $ _x $ _x $ fe $ _2 $ _2 $ o $ $ $ _4 $ nanoparticles（$ 0 \ leq x x \ leq x $ leq 1 $）。通过外壳中的co $^{2+} $的含量调整磁各向异性，提供了一种精确的工具，可以控制TMR的双态状态之间的开关场。通过这种方式，可以设想使用所需的MagnEtotRansport响应来优化软/硬/软/软芯/外壳配置的不同组合。
We report the precise control of tunneling magnetoresistance (TMR) in devices of self-assembled core/shell Fe$_3$O$_4$/Co$_{1-x}$Zn$_x$Fe$_2$O$_4$ nanoparticles ($0\leq x\leq 1$). Adjusting the magnetic anisotropy through the content of Co$^{2+}$ in the shell, provides an accurate tool to control the switching field between the bistable states of the TMR. In this way, different combinations of soft/hard and hard/soft core/shell configurations can be envisaged for optimizing devices with the required magnetotransport response.
