Observation of exchange bias in nanoscale AuFe alloy film

Materials Research Express, 2020
We report on observation of the exchange bias effect in AuFe co-sputtered alloy films in the as-deposited state and following swift heavy ion irradiation. The Mössbauer spectrum for the as-deposited film shows a broad paramagnetic doublet together with a

Detector Response to Swift Heavy Ions [PDF]

, 1989
Track theory is a description of the structure of particle tracks which characterizes the response of many different sorts of detectors to energetic heavy ions. It is a parametric rather than a mechanistic description.
