Beschreibung:
  • Using force spectroscopy in the dynamic mode at low temperature, we have measured the interaction between a magnetic tip and an individual single vortex trapped by an artificial columnar defect in a Bi 2Sr 2CaCu 2O 8+δ single crystal. From spectroscopy data obtained along a line that intersects a vortex, we get quantitative information about the vertical and lateral magnetostatic forces between tip and vortex. Particularly, we estimate the lateral dragging force exerted on the vortex by the magnetic tip to about 1.5 pN. © 2004 American Institute of Physics.
