Summary: | Here we discuss a non-destructive technique that characterizes spin and charge transport at the nanometer scale, across buried layers and interfaces, in magnetic memory elements as used in spin transfer torque based Magnetic Random Access Memory (STT-MRAM). While probing in the current-perpendicular-to-plane direction, this method enables quantification of essential spin transport parameters as length and time scale, spin polarization in buried layers and interfaces, visualization of domain wall evolution across buried interfaces, besides investigating the homogeneity of transport, at the nanoscale, in spintronics devices. |
