Coherent Spin Pumping in a Strongly Coupled Magnon-Magnon Hybrid System Open
We experimentally identify coherent spin pumping in the magnon-magnon hybrid modes of yttrium iron garnet/permalloy (YIG/Py) bilayers. By reducing the YIG and Py thicknesses, the strong interfacial exchange coupling leads to large avoided …

Measurement of spin mixing conductance in Ni81Fe19/<i>α</i>-W and Ni81Fe19/<i>β</i>-W heterostructures via ferromagnetic resonance Open
We present measurements of interfacial Gilbert damping due to the spin pumping effect in Ni81Fe19/W heterostructures. Measurements were compared for heterostructures in which the crystallographic phase of W, either α(bcc)-W or β(A15)-W, wa…

Characterization of spin relaxation anisotropy in Co using spin pumping Open
Ferromagnets are believed to exhibit strongly anisotropic spin relaxation, with relaxation lengths for spin longitudinal to magnetization significantly longer than those for spin transverse to magnetization. Here we characterize the anisot…

Spin pumping damping and magnetic proximity effect in Pd and Pt spin-sink layers Open
We investigated the spin pumping damping contributed by paramagnetic layers\n(Pd, Pt) in both direct and indirect contact with ferromagnetic\nNi$_{81}$Fe$_{19}$ films. We find a nearly linear dependence of the\ninterface-related Gilbert da…

Wave-Number-Dependent Gilbert Damping in Metallic Ferromagnets Open
A wave-number-dependent dissipative term to magnetization dynamics, mirroring the conservative term associated with exchange, has been proposed recently for ferromagnetic metals. We present measurements of wave-number-(k-)dependent Gilbert…

Static and Dynamic Magnetization of Gradient FeNi Alloy Nanowire Open
FeNi binary nanowires with gradient composition are fabricated by the electrodeposition method. The energy dispersive spec-trometer line-sweep results show that the composition changes gradually along the wire axis. The gradient FeNi nanow…
