▲ [14p-A501-2] In-plane magnetization switching detected by spin torque ferromagnetic resonance
Keywords:spintronics, spin dynamics
Magnetization switching using spin orbit torque (SOT) have been investigated intensively, because it enables a low power consumption and high endurance magnetoresistive random access memory. For the in-plane magnetization materials, fabrication of spin valves such as a magnetic tunnel junction is generally required. Such additional and complicated fabrication procedures impede a wide variety of material search for spin orbit materials. In this study, we demonstrated in-plane magnetization switching of a single Ni80Fe20 (Py) layer on platinum (Pt) layer by using the spin rectification effect under ferromagnetic resonance (FMR) condition and a successful magnetization switching was confirmed above 1.55×107 A/cm2. In the presentation, we will also report relationship between detection sensitivity of the magnetization switching and size of the ferromagnetic layer.
