Nuclear magnetic resonance force microscopy at millikelvin temperatures
Promotor: T.H. Oosterkamp
MRFM combines the principles of magnetic resonance and atomic force microscopy.
Setup: Static Magnetic Field with Low Noise
Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…
Advances in SQUID-detected Magnetic Resonance Force Microscopy
In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).
Quantum to Classical
In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.
Setup: Low Temperatures
A lot of our research is performed at temperatures close to absolute zero, among other reasons because this increases the sensitivity of the measurements.
By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.
