dc.description.abstract <p>Low-temperature crystal structure of the Er<sub>x</sub>Dy<sub>1−x</sub>Al<sub>2</sub> alloys with x = 0.45, 0.67, 0.90 was examined using temperature-dependent powder X-ray diffraction. The Er-rich sample, Er<sub>0.9</sub>Dy<sub>0.1</sub>Al<sub>2</sub>, exhibits a rhombohedral distortion associated with the magnetic ordering that occurs around 20 K. The rhombohedral distortion is suppressed in Er<sub>0.67</sub>Dy<sub>0.33</sub>Al<sub>2</sub>, while a weak low-temperature tetragonal distortion is observed in Er<sub>0.45</sub>Dy<sub>0.55</sub>Al<sub>2</sub>. The mean-field theory supports the correlation between the type of structural distortion and the variable easy magnetization axis in Er<sub>x</sub>Dy<sub>1−x</sub>Al<sub>2</sub> intermetallics.</p>
