Magnetic phase diagram of complex Dy/Ho rare-earth heterostuctures
Rare-earth (RE) materials such as Er, Dy and Ho are well-known structures where complex magnetic structures exist as a competition of indirect exchange coupling of localized 4f electrons, anisotropic crystalline field and magnetoelastic interactions. In thin films and heterostructures thanks to reducing of dimensionality and presence of proximity the variety of the magnetic phases can be enriched. Up to now, however, attention was mainly focused on multilayered structures composed of ferromagnetic or helimagnetic RE layers alternating with non-magnetic or ferromagnetic RE, for example, Dy/Y, Ho/Y, Dy/Gd. On the other side, little is known about multilayers composed of two alternating helimagnetic layers. This proposal is aimed on PNR study of magnetic phase diagram of Dy/Ho superlattice comprised of two helical ferromagnets.
