Magnetism on the Nanoscale magnetic force (MFM) and scanning hall probe microscopy (SHPM) Magnetic imaging on small length scales has long been an important asset in fundamental research of various magnetic materials and superconductors. Spearheaded by Bitter decoration in the 1960's, magnetic imaging is nowadays ruled by much more sophisticated techniques such as Magnetic Force Microscopy (MFM) and Scanning Probe Microscopy Historically, the Magnetic Force Microscope (MFM) has been derived from the Atomic Force Microscope (AFM) one year after its invention in 1986. Unlike AFM, MFM uses a magnetic...

attoMFM I low temperature magnetic force microscope, cantilever based The attoMFM I is a compact magnetic force microscope designed particularly for applications at low and ultra low temperature. Based on the attoAFM I the instrument works by scanning the sample below a fixed magnetic cantilever. The magnetic force gradient acting on the tip is then determined by measuring the change in resonance frequency (FM mode) or phase of the cantilever (PM mode) with highest precision using a fiber-based optical interferometer. Both measurement techniques are applied at a certain tip-sample distance, typically...

attoSHPM low temperature scanning Hall probe microscope The attoSHPM is a compact scanning Hall probe microscope, designed particularly for operation at low temperature and high magnetic fields. At the heart of the attoSHPM, a molecular beam epitaxy (MBE) grown GaAs/AlGaAs​Hall sensor measures magnetic fields with unrivalled sensitivity. Local measurements of the magnetization of a sample are obtained by scanning the sample underneath the Hall sensor and simultaneously recording the Hall voltage, directly yielding the local magnetic field. While other local probes may outperform the Hall sensor...
