A geometry for optimizing nanoscale magnetic resonance force microscopy

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...

Nanoscale mechanics by tomographic contact resonance atomic force microscopy.

We report on quantifiable depth-dependent contact resonance AFM (CR-AFM) measurements over polystyrene-polypropylene (PS-PP) blends to detail surface and sub-surface features in terms of elastic modulus and mechanical dissipation. The depth-dependences of the measured parameters were analyzed to generate cross-sectional images of tomographic reconstructions. Through a suitable normalization of ...

NMR Spectroscopy for Thin Films by Magnetic Resonance Force Microscopy

Nuclear magnetic resonance (NMR) is a fundamental research tool that is widely used in many fields. Despite its powerful applications, unfortunately the low sensitivity of conventional NMR makes it difficult to study thin film or nano-sized samples. In this work, we report the first NMR spectrum obtained from general thin films by using magnetic resonance force microscopy (MRFM). To minimize th...
