Influence of Stripe Height on Critical Current Density of Spin-Torque Noise in Tunneling Magnetoresistive Read Heads

Abstract

This paper describes the influence of the stripe height on the critical current density of the spin-torque (ST) noise in the TMR heads using the GHz range noise spectra in detail. The critical current density above which the non-thermal fluctuation noise originates from the ST slightly increases, linearly decreases, becomes minimum, and further keeps… (More)
