Thermal Cycling and Growth of the Martensite Studied by NMR in an Ag-Cd Alloy

P. Scherrer , S. Rubini , C. Dimitropoulos , F. Borsa

113Cd NMR measurements in two Ag-Cd samples cycled between room temperature and temperatures below Ms are presented. The growth curve of the martensite on cooling presents a discontinuity in the cycling temperature region. It is shown that the method of analysis of the NMR data recently developed by us [Phys.Rev.B 46, 10563 (1992)], allows to detect subtle memory effects and the absolute determination of the fraction of the martensite in thermoelastic equilibrium with the parent phase at fixed temperature.
