Dephasing of Transverse Spin Current in Ferrimagnetic Alloys
Youngmin Lim, Behrouz Khodadadi, Jie-Fang Li +3
It has been predicted that transverse spin current can propagate coherently (without dephasing) over a long distance in antiferromagnetically ordered metals. Here, we estimate the…
Conductivity-Like Gilbert Damping due to Intraband Scattering in Epitaxial Iron
Behrouz Khodadadi, Anish Rai, Arjun Sapkota +15
Confirming the origin of Gilbert damping by experiment has remained a challenge for many decades, even for simple ferromagnetic metals. In this Letter, we experimentally identify G…
Spontaneous decay of a soft optical phonon in the relaxor ferroelectric PbMgNbO
C. Stock, P. M. Gehring, R. A. Ewings +4
We report the spontaneous decay of a soft, optical phonon in a solid. Using neutron spectroscopy, we find that specific phonon lifetimes in the relaxor PbMgNbO$_{3}…
Crafting the strain state in epitaxial thin films: A case study of CoFe2O4 films on Pb(Mg,Nb)O3-PbTiO3
Zhiguang Wang, Yaojin Wang, Haosu Luo +2
The strain dependence of electric and magnetic properties has been widely investigated, both from a fundamental science perspective and an applications point of view. Electromechan…
Evidence for anisotropic polar nanoregions in relaxor PMN: A neutron study of the elastic constants and anomalous TA phonon damping
C. Stock, P. M. Gehring, H. Hiraka +6
We use neutron scattering to characterize the acoustic phonons in the relaxor PMN and demonstrate the presence of an anisotropic damping mechanism directly related to short-range,…
Aging associated domain evolution in the orthorhombic phase of <001> textured (K0.5Na0.5)Nb0.97Sb0.03O3 ceramics
Jianjun Yao, Jiefang Li, D. Viehland +2
An aging effect due to a domain evolution in (K0.5,Na0.5)Nb0.97Sb0.03O3 <001> textured ceramics was investigated by piezoresponse force microscopy. We find that such an aging effec…
