The PPMS-AFM/MFM is an alignment-free Atomic Force Microscopy system that can be adapted to the PPMS and it is equipped with a Fibre Interferometer operating at 1310 nm, 15 fm/√Hz noise level with an operation range of 4-300K, and up to 16T magnetic field.
The alignment-free design creates a user friendly utilization; the Fibre Interferometer carries the light by means of a fibre cable with respect to the end of the cantilever, and is used to measure the deflection of the cantilever;
meanwhile which is providing a 10nm magnetic resolution at 4K. Alignment chips with three protrusions compatible with commercial cantilevers eliminate the need of optical alignment by the end user.
The PPMS-AFM/MFM allows the characterization of materials by offering various imaging modes; Scanning Hall
Probe Microscopy, Magnetic Force Microscopy, Electric Force Microscopy, Kelvin Probe Force Microscopy, Conductive AFM.
The instrumentation and the unique design of the PPMS-AFM/MFM microscope allows it to be customized for different cryostat dimensions.
The microscope head consists of two concentrical piezotubes; the inner piezo tube for scanning and the outer for sample positioning.
The scanning piezo is composed of quadrant electrodes and a dither piezo to dither the cantilever and comes with three different options upon request.
The sample approach is done by a stick-slip motion; allowing 10mm motion in Z and Ø3mm in XY, with a sensitivity of 50nm.
Electronic signals are generated by the powerful PPMS-AFM/MFM elctronic via BNC outputs; transferred to the microscope through LEMO connections.
