Magnetic resonance force microscopy with a paramagnetic probe

Distinguishing magnetic and electrostatic interactions by a Kelvin probe force microscopy–magnetic force microscopy combination

The most outstanding feature of scanning force microscopy (SFM) is its capability to detect various different short and long range interactions. In particular, magnetic force microscopy (MFM) is used to characterize the domain configuration in ferromagnetic materials such as thin films grown by physical techniques or ferromagnetic nanostructures. It is a usual procedure to separate the topograp...

Single Spin Magnetic Resonance Force Microscopy

Imaging using Magnetic Resonance Force Microscopy

We demonstrate one-dimensional nuclear magnetic resonance imaging of the semiconductor GaAs with 170 nanometer slice separation and resolve two regions of reduced nuclear spin polarization density separated by only 500 nanometers. This is achieved by force detection of the magnetic resonance, Magnetic Resonance Force Microscopy (MRFM), in combination with optical pumping to increase the nuclear...

Advances in Magnetic Resonance Force Microscopy

Over the years magnetic resonance techniques have demonstrated to be powerful structural characterization and diagnostic imaging tools that have had a profound impact in medicine, biology, chemistry, material science and physics. While NMR provides the ability to perform molecular structure determination by investigating the local surroundings of atoms and the binding characteristics of molecul...

Fast magnetic resonance force microscopy with Hadamard encoding

We present a spatial encoding technique for magnetic resonance force microscopy that allows for a much enhanced image acquisition rate. The technique uses multiplexing, based on spatial Hadamard encoding, to acquire several slices of the image simultaneously and at an undiminished signal-to-noise ratio. We demonstrate an improvement in imaging time by a factor of 7.6, and further advances can b...
