Paper Abstract

In light of the growing interest in spin-related phenomena and devices, there is now renewed interest in the science and engineering of narrow gap semiconductors. In this work, time resolved spectroscopy of InSb-based parabolic multi-quantum wells and narrow gap ferromagnetic alloys grown by MOVPE, have been pursued. In addition, in this study, we report on CR experiments carried out on the ferromagnetic InMnAs film, on which clear resonance signals have been successfully observed in high magnetic fields. Investigation of the electronic structure of III-Mn-V alloys by techniques such as the cyclotron resonance can shed important light on the origin of ferromagnetism and the p-d exchange interaction in III-Mn-V systems. Our results are important for understanding the electronic and magnetic states in these material systems.
