Electric-field-induced spin resonance in antiferromagnetic insulators: Inverse process of the dynamical chiral magnetic effect

We propose a realization of the electric-field-induced antiferromagnetic resonance. We consider threedimensional antiferromagnetic insulators with spin-orbit coupling characterized by the existence of a topological term called the θ term. By solving the Landau-Lifshitz-Gilbert equation in the presence of the θ term, we show that, in contrast to conventional methods using ac magnetic fields, the...

Axion Emission by Magnetic-Field Induced Conversion of Longitudinal Plasmons

Magnetic fields mix axions with photons, allowing for the cyclotron process e → ea by virtue of an intermediate plasmon even if axions do not couple to electrons at tree level. The axion and longitudinal-plasmon dispersion relations always cross for a certain wave-number, leading to a resonant enhancement of this process. Even then, however, it cannot quite compete with the usual nucleon proces...

Current-induced magnetic resonance phase imaging.

Electric current-induced phase alternations have been imaged by fast magnetic resonance image (MRI) technology. We measured the magnetic resonance phase images induced by pulsed current stimulation from a phantom and detected its sensitivity. The pulsed current-induced phase image demonstrated the feasibility to detect phase changes of the proton magnetic resonance signal that could mimic neuro...
