Selected Applications
attoSHPM
Domain Imaging in BaFeO
The 15 µm x 15 µm sized image shows a sample of BaFeO recorded with
an attoSHPM, recorded at 4.2 K. The SHPM sensor was kept in a constant
height of about 200 nm. The color scale spans 106 mT (dark to bright),
while the S/N ratio of this measurement yields an exceptional 50 000:1.
Note that SHPM records absolute field strength as opposed to MFM tech-
niques, that record only field gradients.

Vortex Imaging via Scanning Hall Probe Microscopy
SHPM measurements on a degraded Bi 2 Sr 2 CaCu 2 O 8+x substrate have been
performed demonstrating strong surface pinning effects at 4.2 K and
2.5 Gauss external magnetic field. The figure shows the vortex distribu-
tion measured in constant height of approx. 100 nm above the surface.
