Magnon currents excited by the spin Seebeck effect in ferromagnetic EuS thin films
M. Xochitl Aguilar-Pujol, Sara Catalano, Carmen González-Orellana +7
A magnetic insulator is an ideal platform to propagate spin information by exploiting magnon currents. However, until now, most studies have focused on YFeO (YIG) an…
Spin Hall magnetoresistance effect from a disordered interface
Sara Catalano, Juan M. Gomez-Perez, M. Xochitl Aguilar-Pujol +4
The Spin Hall magnetoresistance (SMR) emerged as a reference tool to investigate the magnetic properties of materials with an all-electrical set-up. Its sensitivity to the magnetiz…
Paramagnetic spin Hall magnetoresistance
Koichi Oyanagi, Juan M. Gomez-Perez, Xian-Peng Zhang +9
Spin Hall magnetoresistance (SMR) refers to a resistance change in a metallic film reflecting the magnetization direction of a magnet attached to the film. The mechanism of this ph…
Strong interfacial exchange field in a heavy metal/ferromagnetic insulator system determined by spin Hall magnetoresistance
Juan M. Gomez-Perez, Xian-Peng Zhang, Francesco Calavalle +9
Spin-dependent transport at heavy metal/magnetic insulator interfaces is at the origin of many phenomena at the forefront of spintronics research. A proper quantification of the di…
Differences in the magnon diffusion length for electrically and thermally driven magnon currents in YFeO
Juan M. Gomez-Perez, Saül Vélez, Luis E. Hueso +1
Recent demonstration of efficient transport and manipulation of spin information by magnon currents have opened exciting prospects for processing information in devices. Magnon cur…
Absence of evidence of spin transport through amorphous YFeO
Juan M. Gomez-Perez, Koichi Oyanagi, Reimei Yahiro +4
Long-distance transport of spin information in insulators without long-range magnetic order has been recently reported. Here, we perform a complete characterization of amorphous Y$…
Spin-Hall magnetoresistance in a low-dimensional magnetic insulator
Saül Vélez, Vitaly N. Golovach, Juan M. Gomez-Perez +5
We observe an unusual behavior of the spin Hall magnetoresistance (SMR) measured in a Pt ultra-thin film deposited on a ferromagnetic insulator, which is a tensile-strained LaCoO3…
Synthetic antiferromagnetic coupling between ultra-thin insulating garnets
Juan M. Gomez-Perez, Saül Vélez, Lauren McKenzie-Sell +8
The use of magnetic insulators is attracting a lot of interest due to a rich variety of spin-dependent phenomena with potential applications to spintronic devices. Here we report u…
Thermally Driven Long Range Magnon Spin Currents in Yttrium Iron Garnet due to Intrinsic Spin Seebeck Effect
Brandon L. Giles, Zihao Yang, John S. Jamison +5
The longitudinal spin Seebeck effect refers to the generation of a spin current when heat flows across a normal metal/magnetic insulator interface. Until recently, most explanation…
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…
