Abstract:

The research contributes to an understanding of the interactions responsible for the magnetic behavior of rare earth alloys on the atomic level as an essential step in correlating the basic interactions with the bulk properties of such alloys. Nuclear hyperfine magnetic NHM and quadrupolar NHQ interaction studies were performed using the 161Dy Mossbauer resonance in the magnetic system DyxGd1-x. The NHM and NHQ interactions were measured as a function of concentration and temperature up to the Neel Curie points. The data for internal field strengths are compared to existing molecular field and spin-wave theories. Modified author abstract
