| 内容記述 | We report magnetoresistance of 40%, corresponding to 80% spin polarization, at magnetic field of 0.5 T and 200 K for oleic acid-coated Fe2.5Mn0.5O4 nanocrystals (FMO NCs) self-assembled on a SiO2/Si substrate by drop casting fabrication. TheFMONCs exhibited spin glass transition around 150 K and nonlinear current voltage (I V) characteristics. Fowler Nordheim plot of the I V characteristics indicated that electrons tunnel directly barriers between the FMO NCs. Transmission electron microscopy revealed that the FMO NCs are elongated hexagon in shape with size of ∼15 20 nm. The FMO NCs self-assembled in two-dimension hexagonal networks of collinear ferromagnetic moments. The [111] easy magnetization axis of each FMO NC was parallel to each other in the hexagonal arrays. Geometrically frustrated lattice of collinear ferromagnetic moments supports both a low and a high intergranular tunneling conductance for the self-assembled FMO NCs without and with magnetic fields, respectively. | |||||
