atto3DR 3-dimensional rotator for in-situ operation The atto3DR double rotation module provides access to full magnetic field (e.g. 9 T) in all directions relative to the sample surface. This is a feature which is unheard of even with significantly more expensive 2D/3D vector magnet setups, simply because split coil configurations do not achieve such high field values. The module comes fully wired and equipped with a convenient leadless ceramic chip carrier (LCCC) socket with 20 contacts, which makes sample exchange a quick and easy task. Of course all parts are non-magnetic, and it is compatible...

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...
