Orbitronics is an emerging field in which orbital currents are used to develop high-efficiency electronic information devices. Orbital have a wider material range and longer transmission distance than spin currents. However, the efficient utilization of remains challenging. In this paper, study reports giant effective Hall angle Ti/Pt metallic heterostructure for magnetization switching. The Ti/Pt/Permalloy (Ni81Fe19) reaches 2.4 ± 0.5, 14-fold increase relative that Ti/Ni. By constructing...
Magnonics has long been hailed as a promising technology poised to overcome the heat dissipation challenges in traditional electronic devices. With escalating integration level of magnon devices, demand arises for lower external field excitation conditions, coupled with enhanced coherence and frequency-selective characteristics. In this proposal, we suggest introducing localized perpendicular magnetic anisotropy nanofilm stack into spin-wave transmission channel finely regulate propagation...
Abstract Although the spin Hall effect provides a pathway for efficient and fast current‐induced manipulation of magnetization, application spin–orbit torque magnetic random access memory with low power dissipation is still limited to materials angles or very high resistivities. This work reports group materials, Pt 1 −x (TiO 2 ) x nanocomposites, that combines giant resistivity. The angle in an yttrium iron garnet/Pt double‐layer heterostructure estimated from combination ferromagnetic...
Orbital angular momentum flow can be used to develop a low-dissipation electronic information device by manipulating the orbital current. However, efficiently generating and fully harnessing currents is formidable challenge. In this study, an approach presented that induces colossal current gradient oxidation in Pt/Ta enhance spin-orbit torque (SOT) achieve high-efficiency magnetization switching. The maximum efficiency of SOT before after Ta improved relative Pt ≈600 1200%, respectively....
A spin Hall effect (SHE) enables the electrical generation and detection of currents for promising applications in spintronics, but heavy metals with low angle θSH limit development SHE devices. In this work, we have introduced dielectric oxide material SrTiO3 into Pt by magnetron sputtering measured on NiCo/Pt1–x(STO)x heterostructure through spin-torque ferromagnetic resonance. Our results demonstrate that maximum Pt0.98(STO)0.02 is 0.121 ± 0.003, which approximately twice pure (0.064...
Spin–orbit torque (SOT) has emerged as an effective means of manipulating magnetization. However, the current energy efficiency SOT operation is inefficient due to low damping-like per unit bias. In this work, we dope conventional rare earth oxides, GdOy, into highly conductive platinum by magnetron sputtering form a new group spin Hall materials. A large spin–orbit (DL-SOT) about 0.35 ± 0.013 obtained in Pt0.70(GdOy)0.30 measured spin-torque ferromagnetic resonance (ST-FMR) technique, which...
The isotropic transmission of magnetostatic forward volume spin waves in magnetic films with perpendicular anisotropy (PMA) is shown to be useful the implementation magnon-based micro-conduits. However, our knowledge, non-magnetic-bias-field spin-wave propagation a PMA insulator has not been achieved yet, which constrains development magnonic information devices and systems. Herein, we demonstrate robust, bias-free an 18.5-μm-thick bismuth-doped thulium iron garnet film PMA. This...
