We study the exchange between electron and magnon spins at interface of an antiferromagnet a heavy metal finite temperatures. The underlying physical mechanism is based on spin torque associated with creation/annihilation thermal magnons right-hand left-hand polarization. process depends strongly relative orientation polarization spins. For sufficiently strong spin-transfer (STT), conversion be...
Pumping viscous fluids using centrifugal pumps in the subsea industry is very common. The pump performance degrades drastically when viscosity of increases, which ultimately gives rise to installation and oil production cost. Their design optimization can lead a significant improvement their performance. Therefore, this study presented effect impeller geometry on pumping fluid through optimizat...
We present a study of the interaction mechanisms in magnetic trilayer structures with an MgO barrier grown by molecular beam epitaxy. The interlayer exchange coupling, Aex, is determined using SQUID magnetometry and ferromagnetic resonance (FMR), displaying an unexpected oscillatory behaviour as the thickness, tMgO, is increased from 1 to 4 nm. Transmission electron microscopy confirms the cont...
Development of efficient soft x-ray laser plasma amplifiers adapted to seeded operation, requires a better control over amplifier transverse spatial extent, brilliance control and gain lifetime. Here it is shown that pumping the plasma amplifier with one long and two short pump pulses (1L2S) provides advantages in terms of control for the specified parameters in the case of Ni-like Ag x-ray las...
Degenerate networks, in which structurally distinct elements can perform the same function or yield the same output, are ubiquitous in biology. Degeneracy contributes to the robustness and adaptability of networks in varied environmental and evolutionary contexts. However, how degenerate neural networks regulate behavior in vivo is poorly understood, especially at the genetic level. Here, we id...
