摘要：

Synthetic Gd/Dy superlattices show novel magnetic properties which we investigate both experimentally and theoretically. In this system competing exchange and Zeeman interactions lead to many different possible magnetic structures. Of particular interest is an alternating-helicity phase where the magnetic unit cell is twice the length of the chemical unit cell. A simple theoretical model gives results in good agreement with the experimental measurements. © 1990 The American Physical Society.
