The researchers used a combination of advanced electronic structure calculations,
magnetic property measurements, and revolving scanning transmission electron microscopy (revolving STEM) to see what was happening at the atomic scale in NiFeCrCo.

Previously, the most precise
measurement of the constant was indirect, relying on a
measurement of the electron's
magnetic properties and using complex theoretical calculations to infer the constant's value.
Capture of all the transmitted electrons allows quantitative
measurement of materials
properties, such as internal electric and
magnetic fields, which are important for use of the materials in memory and electronics applications.
The researchers were permitted by the National Park Service to collect one new rock sample to analyze its
magnetic properties, and added this to existing
measurements made over 30 years ago from a few other sections of the tower.
By means of material - dependent
measurements over a wide temperature range and with a varied thickness of the employed
magnetic material, a direct correlation between the amplitude of the voltage signal and the intrinsic
properties of magnons was identified.
