Probing low-energy hyperbolic polaritons in van der Waals crystals with an electron microscope
Alexander A. Govyadinov, Andrea Konečná, Andrey Chuvilin +8
Van der Waals (vdW) materials exhibit intriguing structural, electronic and photonic properties. Electron Energy Loss Spectroscopy (EELS) within Scanning Transmission Electron Micr…
Tunable sign change of spin Hall magnetoresistance in Pt/NiO/YIG structures
Dazhi Hou, Zhiyong Qiu, Joseph Barker +7
Spin Hall magnetoresistance (SMR) has been investigated in Pt/NiO/YIG structures in a wide range of temperature and NiO thickness. The SMR shows a negative sign below a temperature…
Weak de-localization in graphene on a ferromagnetic insulating film
Luca Pietrobon, Lorenzo Fallarino, Andreas Berger +3
Graphene has been predicted to develop a magnetic moment by proximity effect when placed on a ferromagnetic film, a promise that could open exciting possibilities in the fields of…
Competing effects at Pt/YIG interfaces: spin Hall magnetoresistance, magnon excitations and magnetic frustration
Saül Vélez, Amilcar Bedoya-Pinto, Wenjing Yan +2
We study the spin Hall magnetoresistance (SMR) and the magnon spin transport (MST) in Pt/Y3Fe5O12(YIG)-based devices with intentionally modified interfaces. Our measurements show t…
A two-dimensional spin field-effect transistor
Wenjing Yan, Oihana Txoperena, Roger Llopis +3
The integration of the spin degree of freedom in charge-based electronic devices has revolutionised both sensing and memory capability in microelectronics. Further development in s…
Frequency driven inversion of tunnel magnetoimpedance in magnetic tunnel junctions
Subir Parui, Mário Ribeiro, Ainhoa Atxabal +5
Magnetic tunnel junctions (MTJs) are basic building blocks for devices such as magnetic random access memories (MRAMs). The relevance for modern computation of non-volatile high-fr…
Tuning the spin Hall effect of Pt from the moderately dirty to the superclean regime
Edurne Sagasta, Yasutomo Omori, Miren Isasa +5
We systematically measure and analyze the spin diffusion length and the spin Hall effect in Pt with a wide range of conductivities using the spin absorption method in lateral spin…
Ultra-confined acoustic THz graphene plasmons revealed by photocurrent nanoscopy
Pablo Alonso-Gonzalez, Alexey Y. Nikitin, Yuanda Gao +14
Terahertz (THz) fields are widely applied for sensing, communication and quality control. In future applications, they could be efficiently confined, enhanced and manipulated - wel…
