Low temperature behavior of magnetic domains observed using a magnetic force microscope
A commercial atomic force microscope/magnetic force microscope ~MFM! was modified to cool magnetic samples down to around 100 K under a high vacuum while maintaining its routine imaging functionality. MFM images of a 120 nm thick La0.7Ca0.3MnO3 film on a LaAlO3 substrate at low temperature show the paramagnetic-to-ferromagnetic phase transition. Evolution of magnetic domains and magnetic ripple...
متن کاملPulsed-Current-Induced Domain Wall Propagation in Permalloy Patterns Observed Using Magnetic Force Microscope
Pulsed-current controlled wall motion in 20 m wide 200 m long 160 nm thick patterned Permalloy strips was studied using magnetic force microscopy. By sequential imaging, the displacement of Bloch walls as far as 200 m along the strip was observed. The direction of motion was in the same direction as the carrier velocity, which reversed with current polarity. The displacement per pulse was depen...

متن کاملThe Magnetic Resonance Force Microscope
The emerging technique of magnetic resonance force microscopy (MRFM) (Sidles, 1991) was conceived by Sidles (1992) as a tool that could provide the revolutionary capability for three-dimensional imaging of single-copy biomolecules. This challenging goal has been augmented by a growing interest in applying it to imaging, especially subsurface imaging, of a broad range of materials and devices in...
متن کاملDesign of a self-aligned, wide temperature range (300 mK-300 K) atomic force microscope/magnetic force microscope with 10 nm magnetic force microscope resolution.
We describe the design of a wide temperature range (300 mK-300 K) atomic force microscope/magnetic force microscope with a self-aligned fibre-cantilever mechanism. An alignment chip with alignment groves and a special mechanical design are used to eliminate tedious and time consuming fibre-cantilever alignment procedure for the entire temperature range. A low noise, Michelson fibre interferomet...
