Spin Hall angle quantification from spin pumping and microwave photoresistance
Spin Hall angle quantification from spin pumping and microwave photoresistance
We present a method to quantify the spin Hall angle (SHA) with spin pumping and microwave photoresistance measurements. With this method we separate the inverse spin Hall effect (ISHE) from other unwanted effects for permalloy/Pt bilayers using out-of-plane microwave excitation. Through microwave photoresistance measurements, the in- and out-of-plane precessing angles …
