Theoretical Study of Structure and Energetics of Gold Clusters with the EAM Method

Using the embedded-atom method as developed by Voter and Chen in combination with the variable metric/quasi-Newton and our own Aufbau/Abbau methods, we have identified the three most stable isomers of AuN clusters with N up to 150...

A High-Temperature Mössbauer Study of the Iron Nitrides

Mössbauer spectra of the iron nitrides have been measured at room temperature and at 550ºC. In the case of the room temperature spectrum of γ´-Fe4N, a fit strategy is reviewed which accounts for two spectroscopically inequivalent iron Fe(1) sites due to the simultaneous presence of magnetic and quadrupolar interactions...
