Neutron activation analysis traces copper artifacts to geographical point of origin [PDF]

, 1967
Impurities remaining in the metallic copper are identified and quantified by spectrographic and neutron activation analysis. Determination of the type of ore used for the copper artifact places the geographic point of origin of the ...

Magnetic order and energy-scale hierarchy in artificial spin ice

, 2018
In order to explain and predict the properties of many physical systems, it is essential to understand the interplay of different energy-scales. Here we present investigations of the magnetic order in thermalised artificial spin ice structures, with ...
