- Optical control of magnetism in semiconductors in the ultrafast time scale, AP.R
Abstract
Changing the magnetic state of matter at will and in the ultrashort time scale is a subject of vast contemporary interest. In this project we shall investigate the optical control of magnetism in a variety of semiconductor materials. Light will be used both to induce as well as to monitor the magnetic state. We shall investigate the steady magnetism, as well as the transient one, using ...
- Optical investigation of spintronic systems, AP.R
Abstract
Optical control of magnetic order will be investigated in various materials. Our previous resultsshowed that, in non-magnetic semiconductor quantum dots containing electrons, light can inducemagnetic order, due to the electron-photon interaction, which brings about the alignment, alonga preferential direction, of the spin of the electrons confined in the dots. Our previous results also ...
- Multiple harmonic spectroscopy, spin orientation and instantaneous magnetization using light, AP.R
Abstract
Magnetic semiconductors, with a potential for application in spintronics, will be investigated by spectroscopy of multiple harmonics. The same materials will be investigated to establish the ideal conditions for control of the light induced magnetization, which is a consequence of one of two possible processes: (1) instant magnetization, which persists only while the material is illumin...

- Magneto-optical study of semiconductors for spintronics, BE.PQ
Abstract
Europium chalcogenides are important magnetic semiconductors that have a potential for applications in spintronic devices. Here we shall investigate EuTe and EuSe epitaxial layers, grown by molecular beam epitaxy, to gather new experimental evidence that will improve our understanding of the electronic processes in these systems. The experiments that will be performed include time-resol...
- Magneto-optical investigation of PbEuTe, BE.PQ
Abstract
Europium chalcogenides are important magnetic semiconductors that have a potential for applications in spintronic devices. They share the common property of having a large magnetic moment at the lattice sites occupied by europium, and their magneto-optical properties can be described by the same semi-empirical model, albeit with different parameters. Here we propose to investigate PbEuT...
