Magnetization dynamics in individual magnetite nanocrystals

Probing magnetization dynamics in individual magnetite nanocrystals using magnetoresistive scanning tunneling microscopy.
Amir Hevroni, Boris Tsukerman, and Gil Markovich
Phys. Rev. B 92, 224423 (2015)
(a), (d), and (g) Current vs time measurements performed on the three particles. Each particle was examined at a different temperature (indicated on the figure). In the case of particle 3, the graph shown is one of five consecutive measurements. (b), (e), and (h) Constant current STM topography images of the three particles. (c), (f), and (i) Height profiles of the measured particles, which are marked by arrows.
