Special Session 71: Recent progress in spintronics: Experiment, theory and simulation
Contents
Creating temperature gradients has resulted in a new research direction in spinelectronics -- spincaloritronics. By optical heating using a small laser focus on a magnetic tunnel junction, I show that a large Seebeck voltages can be generated. The tunnel junctions' Seebeck coefficients can be changed by the magnetic configuration. New techniques for the detection of ultrafast spin currents have to be developed to bring spin-based information technology to ultrafast time scales. These can be quanitatively determined by THz emission. The original transient spin-currents can be calculated by the theory of super diffusion.
