The Possibility of Sensor Application of Spin Torque Oscillator

Abstract (in Japanese) (See Japanese page) 
(in English) We discuss the performance of the spin-torque oscillator (STO) as a magnetic field sensor. An MR sensor with magnetic tunnel junctions (MTJs) are investigated for detecting the magnetic field. For magnetic sensor with higher sensitivity, the STO is a promising candidate. In this research, we discuss signal to noise (SN) ratio of MR and STO sensors by employing a theoretical model. We found that the STO sensor may possess a higher SN ratio than that of MR sensor.
