A transfer-rod-mounted rotatable sample holder enabling a compact modular vacuum system for ion-beam milling, oblique magnetron sputtering, and co-sputtering
Tiago de Oliveira Schneider, Folke Kaiser, Andreas Semrad +2
We present a novel multifunctional sample-holder concept for compact research-scale vacuum systems. The sample holder is mounted directly on the transfer rod and remains mechanical…
Thickness-Dependent Orbital-to-Spin Torque Signatures in Cr/Gd/Co Thin Films
Tiago de Oliveira Schneider, Michel Heidkamp, Luana Caron +5
We studied orbital-torque generation in Cr(10nm)/Gd()/Co(3nm)/TaO and the inverted stack Co(3nm)/Gd()/Cr(10nm) with from 0 t…
Terahertz Phase Inversion via Field-Free Spin-Orbit Torque Switching in an Antenna-Integrated Spintronic Heterostructure
Amir Khan, Tiago de Oliveira Schneider, Suraj Joshi +4
We demonstrate microsecond-timescale electrical control of the terahertz (THz) emission phase in broadband field-free spintronic THz emitters, enabling megahertz-rate phase inversi…
Fundamental picture of the conduction mechanism in solid-state polymer electrolytes revealed by terahertz spectroscopy
Johanna Weidelt, Jijeesh Ravi Nair, Diddo Diddens +9
Solid polymer electrolytes (SPEs) based on cross-linked poly(ethylene oxide) (PEO) encompassing lithium salts have gained significant attention as separators in solid-state lithium…
Spin Hall effect in the high-resistivity high-entropy alloy AlCrMoW
Jyoti Yadav, Felix Janus, Tiago de Oliveira Schneider +3
We study thin films of the high-entropy alloy system Al(CrMoW), grown on Ta seed layers by magnetron co-sputtering. Between and , a resistivity larger…
Uniaxial Magnetic Anisotropy and Type-X/Y Current-Induced Magnetization Switching in Oblique-Angle-Deposited Ta/CoFeB/Pt and W/CoFeB/Pt Heterostructures
Amir Khan, Shalini Sharma, Tiago de Oliveira Schneider +1
Planar current-induced magnetization switching (CIMS) driven by spin-orbit torque (SOT) requires an in-plane uniaxial magnetic anisotropy (UMA), which can be induced by oblique-ang…
Enhanced THz emission from spintronic emitters with Pt-Al alloys
Felix Janus, Nicolas Beermann, Jyoti Yadav +5
Platinum (Pt) is the element with the largest spin Hall conductivity and is known as the most efficient spin-to-charge conversion material in spintronic THz emitters. By alloying w…
Emergent spin Hall conductivity in Tantalum-Rhenium alloys
Felix Janus, Jyoti Yadav, Nicolas Beermann +5
We investigate the spin Hall conductivity (SHC) of a composition series of a Ta-Re bcc solid solution. At approximately 60 at.% Ta the Ta-Re alloy features an SHC similar to bcc-W,…
Efficient Spintronic THz Emitters Without External Magnetic Field
Amir Khan, Nicolas Sylvester Beermann, Shalini Sharma +4
We investigate the performance of state-of-the-art spintronic THz emitters (W or Ta)/CoFeB/Pt with non-magnetic underlayer deposited using oblique angle deposition. The THz emissio…
OpenFMR: A low-cost open-source broadband ferromagnetic resonance spectrometer
Markus Meinert, Tiago de Oliveira Schneider, Shalini Sharma +1
We describe a broadband ferromagnetic resonance spectrometer for scientific and educational applications with a frequency range up to 30 GHz. It is built with low-cost components a…
