【 摘 要 】

Singte-crystal alloys of HoxTm1-x were grown using the molecular beam epitaxy technique. The components of the magnetic moments along the c-direction and in the basal plane were obtained using neutron diffraction, and the magnetic structures of this system have been determined. The results were compared with calculations based on a mean-field model, and the theoretical predictions axe in good agreement with the experimental results. The existence of the penta-critical point at x(c) = 0.325 and T-c = 67.85 K, which was also predicted by the mean-field model was confirmed by the experimental results. (C) 2001 Elsevier Science B.V.
