Magnetic exchange force microscopy with atomic resolution
Article Abstract:
Magnetic exchange force microscopy could reveal the arrangement of both surface atoms and their spins simultaneously for a prototypical antiferromagnetic insulator, the (001) surface of nickel oxide. The use of external magnetic field to align the magnetic polarization at the tip apex allows observing the direct magnetic exchange coupling between the spins of the tip atom and sample atom that are closest to each other.

Same old magnetism
Article Abstract:
Studies have shown on the basis of latitudes at which ancient salt deposits occur that the Earth's magnetic field has always aligned along its rotation axis. They suggest the possible implication that ancient global glaciations were not caused by a realignment of this axis.
