    Notes: Highly ordered MnPt3 alloy film was grown by molecular-beam epitaxy (MBE) at a temperature of 300 °C. The MnPt3 film exhibits a large Kerr rotation, which reaches a maximum value of −0.7° at 1.24 eV. MnPt3(2 nm)/Co(0.6 nm) multilayers were also grown by MBE method onto MgO(111) substrates at a temperature of 300 °C. It was verified by the observation of the reflection high-energy electron diffraction patterns that Co and MnPt3 layers in the film were grown epitaxially on MgO(111). The appearance of superlattice line due to Cu3Au structure in x-ray-diffraction patterns confirmed the formation of the ordered phase in the MnPt3 layer. The hysteresis loops for in-plane and film normal directions became close to each other, which implies that the perpendicular magnetic anisotropy was induced through the multilayered structure. The Kerr spectrum of the MnPt3/Co multilayer have a negative peak of −0.26° around 1.4 eV. This value is fairly smaller in magnitude compared to the one estimated by the effective reflectivity method using the optical and the magneto-optical constants for Co and MnPt3 alloy. © 1997 American Institute of Physics.

    Notes: The magnetic and magneto-optical properties have been investigated for ordered (Mn1−xFex)Pt3 alloy (0〈x〈0.6) films, prepared by annealing (Mn-Fe)/Pt multilayer films at 800 °C. The Kerr spectrum of the MnPt3 film had a large negative peak value of −1.18° at 1.24 eV, and showed a small positive peak around 3.2 eV. With increasing Fe content x, the peak value at 1.24 eV decreased in magnitude and the position of the peak shifted towards lower energy side. Furthermore, another peak appeared in the Kerr spectra around 2.3 eV for x〉0.24. The spectral analysis of the diagonal component of dielectric tensor and the off-diagonal component of conductivity tensor showed that all the peaks mentioned above were attributed to interband transitions. © 1997 American Institute of Physics.
