Abstract

The magnetism and transport characterizations of the melt-spun ribbon Cu₂MnAl alloy are presented. The temperature dependence of magnetization agrees well with the spin-wave theory. A qualitative interpretation has been given for the transport properties and led to information about the microscopic scattering mechanisms involved. A negative GMR for Cu₂MnAl ribbons up to 3.5% at high field is reported. The maximal magnetic scattering resistivity is estimated by the magnetic measurements.
