(Color online) (a) Temporal evolutions of the (solid line), (dashed line), and (dotted line) components of the average magnetization for an applied field and a current density (AlO MTJ); (top right) snapshots of magnetization at three different points displayed in (a): A ( minimum, maximum), B ( maximum, z maximum), and C ( minimum, minimum); (b) 3D view of the average magnetization motion of the same process.
(a) Plot of the frequency of microwave oscillations vs the applied field for AlO MTJ (solid line, ) and MgO MTJ (dashed line, ); (b) static hysteresis loop computed by solving the Brown equation; (c) view of the pinhole location in the elliptical cross section of the MTJ.
(Color online) (a) Temporal evolution of the component of average magnetization for an applied field and a current density (MgO MTJ); (b) total spectrum of the above signal computed by means of the MSMT; (top right A–C) snapshots of three different domain configurations of the same dynamic above.
(Color online) (top) Total spectrum of the magnetization dynamics driven by a SPC and a field of (AlO MTJ) together with the 2D spatial distribution of the main mode excited ; (bottom) total spectrum of the magnetization dynamics driven by a SPC and a field of (AlO MTJ), when a squared cross-section pinhole has been introduced in the center of the ellipse, together with the 2D spatial distribution of the main modes excited. The frequencies of the excited modes are 3.56, 5.78, 12, and .
