“…Ferrimagnetic order is common in rare earth-transition metal alloys, such as Fe-Dy. 13 In the present case, ferromagnetic ordering of the Dy could result from the likely intermixing of Dy and NiFe at the interface, or from interfacial exchange across a sharp Dy/NiFe interface.…”

Precessional dynamics of a Co50Fe50(0.7)/Ni90Fe10(5)/Dy(1)/Ru(3) (thicknesses in nm) thin film have been explored by low temperature time-resolved magneto-optical Kerr effect and phase-resolved x-ray ferromagnetic resonance measurements. As the temperature was decreased from 300 to 140 K, the magnetic damping was found to increase rapidly while the resonance field was strongly reduced. Static x-ray magnetic circular dichroism measurements revealed increasing ferromagnetic order of the Dy moment antiparallel to that of Co50Fe50/Ni90Fe10. Increased coupling of the Dy orbital moment to the precessing spin magnetization leads to significantly increased damping and gyromagnetic ratio of the film while leaving its magnetic anisotropy effectively unchanged.

“…Thin films of rare earth-transition metal (RE-TM) amorphous magnetic alloys are most notable as data storage media because their recording bits are free from grain boundary effects thereby, allowing ultra high areal density memory capacity. These thin films can be easily produced using various coating techniques [1]. In both read and write elements of magnetic recording heads and MRAM devices, fast switching time is becoming relevant for achieving higher data transfer rates.…”

This paper reports on the effect of Sm doping concentration on structural and static magnetic properties of electrodeposited NiFe thin films. A reduction of Ni concentration from 80 to 50 percent was observed as the Sm concentration increased from 0 to 25%. XRD analyses revealed that a transition from crystalline to partially disordered state occurred on the Sm-doped NiFe thin films and ultimately transformed to amorphous state at higher concentration. The saturation magnetization decreased to ~50% at 25% Sm doping as compared to that of NiFe thin films.
