From: Nano spin-diodes using FePt-NDs with huge on/off current ratio at room temperature
Local I-V characteristics of FePt-NDs.
(a) I-V characteristics measured using a CoPtCr-coated AFM-tip with and without application of a magnetic field in the same direction as the initial tip magnetization. Measurement setup is shown in inset. (b) I-V characteristics measured after 30 to 50 min passed after removing the external field. c, I-V characteristics measured under the application of a magnetic field opposite to the first magnetization direction at 4.5 kOe. (d) Schematics of the variation in the directions of magnetization of the FePt-NDs and CoPtCr-cantilever with the application of an external field.
