Microscopy
Microscopy Measurement OptionsQuantum Design and Attocube Systems announced the PPMS SPM – the only Scanning Probe Microscopes certified and endorsed by Quantum Design for use in its respected Physical Property Measurement System (PPMS). The ultra-compact, high resolution PPMS SPM uses advanced technologies such as low temperature compatible objectives for confocal microscopy or a fiber-optical interferometer for force microscopy with outstanding signal-to-noise force detection.
The rugged housing construction is made from highest quality Titanium, ensuring maximum stability and minimum sample drift during variation of temperature and/or magnetic field. The patented driving technology of the coarse positioning system warrants a precise and reliable sample approach and positioning in three axes with nanometer precision over several millimeters range. Plus, the instrument is fully compatible with commercially available AFM/MFM cantilevers.

• Positioning range: 3 × 3 mm
• Scanning range: 12 × 12 μm2
Microscopy Options
• Low Temperature Magnetic Force Microscope (attoMFM Ixs): ultra-compact magnetic force microscope designed particularly for applications at low and ultra low temperature. On the basis of a conventional atomic force microscope, the instrument works by scanning a 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 (AM mode) with highest precision using a fiber-based optical interferometer.
• Low Temperature Atomic Force Microscope (attoAFM Ixs): ultra-compact atomic force microscope designed particularly for applications at low and ultra low temperature. The instrument works by scanning a sample below a fixed cantilever while measuring its deflection with the highest precision using a fiber based optical interferometer. Combined with the ASC500 SPM controller, both contact and noncontact modes are applicable, making the attoAFM Ixs a powerful tool for topographic measurements, force spectroscopy and other imaging modes.
• Low Temperature Scanning Hall Probe Microscope (attoSHPM xs): ultra-compact scanning Hall probe microscope, designed particularly for operation at low temperature and high magnetic fields. At the heart of the SHPM, a molecular beam epitaxy (MBE) grown GaAs/AlGaAs Hall sensor measures magnetic fields with unrivaled 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.
• Low Temperature Confocal Microscope (attoCFM xs): ultra-compact confocal microscope developed to offer the highest flexibility combined with maximum mechanical stability for low temperature confocal microscopy experiments. Can be ordered with either free-beam or fiber based optics. With free-beam optics, excitation and collection ports are completely independent, allowing the introduction of further optical components (e.g. filter or polarizer) and enabling measurements such as Raman spectroscopy. The fiber based setup is designed for the highest mechanical stability, allowing single quantum dot measurements over a time span of several weeks and operation in cryogen-free cryostats.
