Spin caloritronics in a CrBr-based magnetic van der Waals heterostructure
Tian Liu, Julian Peiro, Dennis K. de Wal +4
The recently reported magnetic ordering in insulating two-dimensional (2D) materials, such as chromium triiodide (CrI) and chromium tribromide (CrBr), opens new possibiliti…
Microwave control of thermal magnon spin transport
Jing Liu, Frank Feringa, Benedetta Flebus +4
We observe that an rf microwave field strongly influences the transport of incoherent thermal magnons in yttrium iron garnet. Ferromagnetic resonance in the nonlinear regime suppre…
Efficient spin injection into graphene through trilayer hBN tunnel barriers
Johannes Christian Leutenantsmeyer, Josep Ingla-Aynés, Mallikajurna Gurram +1
We characterize the spin injection into bilayer graphene fully encapsulated in hBN using trilayer (3L) hexagonal boron nitride (hBN) tunnel barriers. As a function of the DC bias,…
Bias dependent spin injection into graphene on YIG through bilayer hBN tunnel barriers
J. C. Leutenantsmeyer, T. Liu, M. Gurram +2
We study the spin injection efficiency into single and bilayer graphene on the ferrimagnetic insulator Yttrium-Iron-Garnet (YIG) through an exfoliated tunnel barrier of bilayer hex…
Observation of spin-valley coupling induced large spin lifetime anisotropy in bilayer graphene
Johannes Christian Leutenantsmeyer, Josep Ingla-Aynés, Jaroslav Fabian +1
We report the first observation of a large spin lifetime anisotropy in bilayer graphene (BLG) fully encapsulated between hexagonal boron nitride. We characterize the out-of-plane (…
Proximity induced room-temperature ferromagnetism in graphene probed with spin currents
J. C. Leutenantsmeyer, A. A. Kaverzin, M. Wojtaszek +1
The introduction and control of ferromagnetism in graphene opens up a range of new directions for fundamental and applied studies. Several approaches have been pursued so far, such…
Comparison of the magneto-Peltier and magneto-Seebeck effects in magnetic tunnel junctions
J. Shan, F. K. Dejene, J. C. Leutenantsmeyer +3
Understanding heat generation and transport processes in a magnetic tunnel junction (MTJ) is a significant step towards improving its application in current memory devices. Recent…
Spin-transfer torque switching at ultra low current densities
Johannes Christian Leutenantsmeyer, Vladyslav Zbarsky, Steffen Wittrock +9
The influence of the tantalum buffer layer on the magnetic anisotropy of perpendicular Co-Fe-B/MgO based magnetic tunnel junctions is studied using magneto-optical Kerr-spectroscop…
Spin-transfer torque switching below 20 kA/cm in perpendicular magnetic tunnel junctions
Johannes Christian Leutenantsmeyer, Marvin Walter, Steffen Wittrock +4
We demonstrate the reduction of critical spin-transfer torque (STT) switching currents in Co-Fe-B/MgO based magnetic tunnel junctions (MTJ) with perpendicular magnetization anisotr…
Parameter space for thermal spin-transfer torque
Johannes Christian Leutenantsmeyer, Marvin Walter, Vladyslav Zbarsky +10
Thermal spin-transfer torque describes the manipulation of the magnetization by the application of a heat flow. The effect has been calculated theoretically by Jia et al. in 2011.…
