Abstract
Face‐centered‐cubic (fcc) Co–Fe alloys in the vicinity of 10 at. % Fe form the basis for an important class of semihard magnetic alloys used for memory and switching applications. The elastic properties are important in determining the magnitude of the internal and/or applied stresses resulting from device operation and processing. The work described was undertaken to evaluate the compositional dependence of the elastic stiffness moduli in the fcc range of stability. The elastic stiffness moduli for single crystals of 6, 12, and 14 at. % Fe were measured by an ultrasonic method previously described (Ref. 3). The results for the 6 at. % Fe alloy at 25°C were c 11=2.340, c 12=1.589, and c 44=1.259×1012 dyn/cm2. The stiffness moduli were found to vary only slightly with composition.This publication has 2 references indexed in Scilit:
