Abstract :
The electric field induced magnetic anisotropy (EMA) has been observed through ferromagnetic resonance (FMR) in magnetic tunnel junctions (MTJs) by varying the DC bias voltage [1,2]. In this work, however, we show that by changing the magnetization and field setup, the effect of EMA in FMR can be observed and distinguished without an application of DC bias voltage.
