First-principles calculation of the exchange interaction and the exchange force between magnetic fe films
TL;DR: In this paper, the exchange interaction and exchange force between two magnetic Fe(100) thin films were investigated and it was shown that the magnitude of the calculated exchange force is of the order of $10-9} $N at 1 < d/a < 1.5, where d is the distance between surfaces of the two thin films and $a$ the lattice constant of bulk Fe.

TL;DR: A pH-sensitive device on a glass substrate based on properties of carbon nanotubes, which can detect pH, is applicable for use as a biosensor through modification of the CNT surface.
Scanning magnetoresistance microscopy with a magnetoresistive sensor cantilever
TL;DR: In this article, a cantilever with a magnetoresistive (MR) sensor is fabricated for scanning magnetoresistance microscope, in order to realize the simultaneous imaging of surface topography and magnetic field distribution.
