Neutron diffraction study of magnetic properties of Dy/Y superlattices

The magnetic properties of MBE-grown Dy/Y superlattices (SLs) have been studied by neutron diffraction. The SL growth direction is at an angle of approximately 35° to the c-axis instead of being along one of the principal axis directions. The results confirm the coexistence of helical antiferromagne...

Zusammenfassung:The magnetic properties of MBE-grown Dy/Y superlattices (SLs) have been studied by neutron diffraction. The SL growth direction is at an angle of approximately 35° to the c-axis instead of being along one of the principal axis directions. The results confirm the coexistence of helical antiferromagnetic order and ferromagnetic order up to the Néel temperature T N ≈ 180 K. This is the first time that ferromagnetism has been observed in Dy/Y superlattices.
