| 中文摘要 | The new ferromagnetic Heusler alloy of Cu2FeAl has been prepared by melt spinning. The band-structure calculations on this alloy predict a ferromagnetic ground state and the crystal structure not to be stable. The intrinsic properties of Cu2FeAl ribbons are described from magnetic and transport measurements. The electronic structure calculations show that the magnetic moment of Cu2FeAl is not localized, which is not the same as Cu2MnAl. At low temperature, the magnetization decreases as T-3/2, as can be well interpreted by spin-wave theory. An interpretation is given for the electrical resistivity and leads to information about the microscopic scattering mechanisms involved. A negative longitudinal magnetoresistance of less than 1% at high field is observed, which can be qualitatively explained by s-d interaction. The magnetic resistivity is estimated for this compound.
