Dimension Icon - ambient AFM microscope - Bruker company , measuring in PeakForce mode providing quantitative or contrast information of Young modulus, adhesion, dissipation and deformation in addition to standard topography (up to 8 channels with 5120 x 5120 points can be measured simultaneously). In the PeakForce mode the tip is oscillating at 2 kHz and the electronics is fast enough to measure in each point force curves from which the nanomechanical properties of the samples can be established.

Magneto‑optical Kerr effect (MOKE): When linearly polarized light reflects from a magnetized surface, the plane of polarization rotates from its original direction. The information depth of the MOKE is 10-15 nm in metals.

The setup is moreover equipped with electrical wireing (8 connections) for transport measurements in a 4-point geometry. 2 additional shielded cables allow to couple high frequency signals, e.g. for surface acoustic waves or other applications.
