Selected Applications Electronics scan controller and software ASC500 (for detailed specifications please see attoCONTROL section) laser LDM1300 laser/detector module (for detailed specifications please see attoCONTROL section) Options closed loop upgrade for coarse positioners resistive encoder, range 5 mm, sensor resolution approx. 200 nm, repeatability 1-2 μm in-situ inspection optics tip/sample monitoring via in-situ LT-LED for illumination, mirrors, lenses and CCD camera (outside of cryostat) field of view approx. 3 mm x 2 mm, res closed loop scanning upgrade interferometric encoders available (see attoDRY LAB -> attoMFM I+) additional AFM head with manual alignment conventional cantilever holder, compatible with standard commercial cantilevers High Resolution MFM on bit patterned media Co-Pd at 10 K MFM measurement on Co-Pd dots with 50 nm diameter at 10 K using the attoMFM I. The image demonstrates the high magnetic resolution achievable with the attoMFM. Variations in magnetic field perpendicular to the surface allows switching domains from one magnetic state to the other (here recorded at 6250 Oe). For this measurement, the attoMFM was operated at constant height with the frequency shift measured using a phase-locked loop.

The image was taken in constant distance mode with the height above the sample surface set to 50 nm. The area shown in the figure corresponds to 15µm x 15µm with a size of 800 x 800 pixel.
