Abstract
Six rare-earth binary-alloy systems have been investigated in a search for Lifshitz points. No such points were found. All systems showed a highest ordering temperature jump when the sample composition went from values favoring helical ordering to values favoring ferromagnetic ordering. It is believed that ferromagnetic nearest-neighbor interactions and antiferromagnetic next-nearest-neighbor interactions are responsible for the observed behavior and that a finiteturn angle jump at the critical concentration will always occur for such systems.
