Abstract: The invention relates to a spin detector arrangement for detecting vector components of a predominating spin vector in a particle beam (T) having a predominating spin orientation of the particles. The spin detector arrangement comprises a spin rotator (1) having a switchable coil (5), wherein the switchable coil (5) comprises an axial direction and is aligned such that the particle beam (T) passes through the switchable coil (5) along the axial direction; a deflection device (7) connected downstream of the spin rotator (1) and deflecting the path of the particle beam (T) electrostatically by a deflection angle; a spin detector (9) connected downstream of the deflection device (7), allowing the deflection of the vector component of the spin vector predominating in the particle beam (T) perpendicular to the direction of motion of the particle beam (T); and a switching unit (15) connected to the switchable coil (5), allowing switching of the excitation state of the coil (5).

Abstract: A metal tip (1) for scanning probe applications is provided. The tip (1) has an axial extension (I), a radial extension (d), a pointy section (B) that extends axially from a section of maximum radial extension (5) to an atomically sharp end (9), and a blunt section (A) that extends axially from the section of maximum radial extension (5) to a blunt end (7), where the axial extension of the pointy section (B) is larger than the axial extension of the blunt section (A) The metal tip (1) has a mass of 10 ?g or less.
