Abstract
The temperature dependence of the , , and Mössbauer effect has been studied in intermediate phases of with the CsCl structure. Our results indicate that the CsCl structure is metastable and undergoes a low-temperature martensitic phase transformation to a close-packed (FeB-like) structure. The ratio of the quantity of the two phases present at 4.2°K for various compounds is obtained. Mössbauer-absorption patterns for in ErAu have a temperature dependence which is characteristic of relaxation effects. Isomer-shift systematics for in for the CsCl and the transformed close-packed phases are discussed.
