“…[32][33][34][35][36][37][38] Alloys combining transition metals (TM) and rare earth (RE) elements exhibit magnetic moments originating from electrons residing in the d and f orbitals, respectively. 39,40 Certain combinations of these elements result in strong antiferromagnetic exchange coupling. These materials can manifest complex magnetic structures with a considerable variation in magnetization, depending on their composition.…”

“…The binary intermetallic DyCo 5 alloy belongs to the family of binary rare-earth (RE)–transition metal (TM) compounds, renowned for their magnetic properties that find applications in permanent magnet technologies, 13 spintronics, 14 and ultrafast optical switching. 15 Particularly, DyCo 5 exhibits remarkable magnetic properties, including a high Curie temperature of approximately 970 K, attributable to the large exchange coupling of Co spins, as well as a high coercive field stemming from a considerably high magnetic anisotropy.…”

Surface acoustic waves (SAWs) are excited by femtosecond extreme ultraviolet (EUV) transient gratings (TGs) in a room-temperature ferrimagnetic DyCo5 alloy. TGs are generated by crossing a pair of EUV pulses from a free electron laser with the wavelength of 20.8 nm matching the Co M-edge, resulting in a SAW wavelength of Λ = 44 nm. Using the pump-probe transient grating scheme in reflection geometry, the excited SAWs could be followed in the time range of −10 to 100 ps in the thin film. Coherent generation of TGs by ultrafast EUV pulses allows to excite SAW in any material and to investigate their couplings to other dynamics, such as spin waves and orbital dynamics. In contrast, we encountered challenges in detecting electronic and magnetic signals, potentially due to the dominance of the larger SAW signal and the weakened reflection signal from underlying layers. A potential solution for the latter challenge involves employing soft x-ray probes, albeit introducing additional complexities associated with the required grazing incidence geometry.

“…Thin films of compensated ferrimagnets based on the combination of rare-earth and transition metals having alloy or multilayer forms are currently considered key materials for spintronics and other modern technology [3]. Thin films of Mn 4 N also demonstrate non-collinear ferrimagnetism and are interesting materials for spintronics applications [4].…”

The experimental discovery of the suppression effect of the non-collinear phase in strong magnetic fields near the compensation point in ferrimagnetic structures was made. The observations were carried out using the magneto-optical method by creating a lateral temperature gradient in the plane of the epitaxial films of iron garnets. The non-collinear phase is absent in weak magnetic fields. If an external magnetic field exceeds the first critical value, the non-collinear phase arises near the compensation point. The temperature range of the non-collinear phase expands due to the field increase up to the second critical value. Further field increases conversely reduce the temperature range of the non-collinear phase so that the field above the second critical value causes the disappearance of the non-collinear phase. The effect of the occurrence and suppression of the non-collinear phase is demonstrated on samples of two types of iron garnet films with two and three magnetic sublattices. Phase diagrams of the magnetic states in the vicinity of the critical point are constructed, and it is shown that the region of existence of the non-collinear phase in a two-sublattice magnet is smaller than in a three-sublattice one.
