Spin polarized scanning tunneling
microscopy (SP-STM) is a specialized application
of scanning tunneling
microscopy (STM) that can provide detailed information of magentic phenomena
on the single atom
scale additional to the atomic topology gained with STM. SP-STM was developed
by Roland Wiesendanger at the University of Hamburg (Germany) and opened a
novel approach to static and dynamic magnetic processes as precise
investigations of domain walls in ferromgnetic and antiferromagnetic systems, as well as thermal and current induced
switching of nanomagnetic particles.
