Static and spherically symmetric black holes in gravity with a background Kalb-Ramond field
Ke Yang, Yue-Zhe Chen, Zheng-Qiao Duan +1
The Lorentz symmetry of gravity is spontaneously broken when the nonminimally coupled Kalb-Ramond field acquires a nonzero vacuum expectation value. In this work, we present exact…
Parametric resonance of spin waves in ferromagnetic nanowires tuned by spin Hall torque
Liu Yang, Alejandro A. Jara, Zheng Duan +4
We present a joint experimental and theoretical study of parametric resonance of spin wave eigenmodes in NiFe/Pt bilayer nanowires. Using electrically detected magnet…
Dimensional crossover in spin Hall oscillators
Andrew Smith, Kemal Sobotkiewich, Amanatullah Khan +9
Auto-oscillations of magnetization driven by direct spin current have been previously observed in multiple quasi-zero-dimensional (0D) ferromagnetic systems such as nanomagnets and…
Nanowire Spin Torque Oscillator Driven by Spin Orbit Torques
Zheng Duan, Andrew Smith, Liu Yang +5
Spin torque from spin current applied to a nanoscale region of a ferromagnet can act as negative magnetic damping and thereby excite self-oscillations of its magnetization. In cont…
Voltage-Induced Ferromagnetic Resonance in Magnetic Tunnel Junctions
Jian Zhu, J. A. Katine, Graham E. Rowlands +8
We demonstrate excitation of ferromagnetic resonance in CoFeB/MgO/CoFeB magnetic tunnel junctions (MTJs) by the combined action of voltage-controlled magnetic anisotropy (VCMA) and…
