Spin torque driven excitation spectra and microwave performances for different STNO configurations Description The dynamic response under spin transfer torque depends on the magnetization configuration of the polarizer and the free layer. At SPINTEC we have focused on two configurations which are (i) a perpendicular polarizer or (ii) a synthetic antiferromagnetic free layer. Partners LETI/DCOS […]
