The magnetic structures of HoxTm1−x thin film alloys

Abstract Single-crystal alloys of Ho x Tm 1− 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 are 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.
