Zusammenfassung: | 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. |
