Накратко на български

Магнитните интерфейси между органични молекули и специални сплави от благородни метали и редкоземни елементи се анализират чрез спектроскопия. Това помага за разработването на бъдещи устройства за квантова обработка на информация и молекулярна спинтроника, като органични спин-клапани.

Magnetic Hybrid Metal-Organic Interfaces

Several experimental and theoretical works have suggested organic semiconducting molecules as an excellent and promising alternative for the development of quantum information processing and molecular spintronic based devices. MagicFACE explores new and exotic spin textured interfaces by using as substrate a non-conventional ferromagnetic surface-alloy, which contains rare earths (RE) atoms and noble metals. The broad number of possible RE atoms used for the preparation of such alloys provides an attractive platform to optimize and tune magnetic metal-organic interfaces. In this context MagicFACE aims to study the interaction at the hybrid metal-organic interface combining a wide variety of spectroscopic approaches with three key scientific objectives: - Demonstration of different hybrid metal-organic interfaces with enhanced magnetic properties prepared on two-dimensional surface alloys with non-conventional ferromagnetism. - Unravel the effect that the formation of the hybrid metal-organic interface has on the magnetic and electronic properties of both the non-conventional ferromagnetic two-dimensional substrate and organic molecular layer. - Disentangle the effect of the magnetic coupling between the ferromagnetic substrate and organic molecular layer on the spin-dependent electronic properties at the interface. The project will have direct and short-term impacts for nanoscience and self-assembly research, and potentially wider and more long-term impacts on development of future effective molecular spintronic-based devices like for example organic spin-valves or spin-organic light emitting diodes (spin-OLEDs).

Цел на проекта

MagicFACE deals on the design and investigation of magnetic hybrid metal-organic interfaces by evaporation of organic molecules (phthalocyanines, porphyrins and single molecular magnets) on non-conventional ferromagnetic surface- confined alloys, which contain rare earths atoms and noble metals (Ag and Au). The project aims to give a full description of the electronic and magnetic interaction phenomena that takes places at the hybrid metalorganic interface, exploring the possibility to create highly spin-polarized surfaces to enhance the performance of quantum information processing and organic spintronic devices. Several spectroscopies and microscopies are combined to obtain a comprehensive understanding on how the hybrid metal-organic interface forms and which kind of electronic and magnetic properties it displays. The preparation of the interface will be carried out under ultra-high vacuum conditions and the structure and morphology will be analyzed using Scanning Tunneling Microscopy and Low Energy Electron Diffraction. The electronic characterization includes local Scanning Tunneling Spectroscopy, spatially averaged Photoelectron Spectroscopy and X-ray absorption Spectroscopy. The main goal is to understand the chemistry and the physical processes taking place at the interface: charge transfer, energy level alignment and hybridization effects. Moreover, the study of the magnetic behaviour of the interface will be carried out by means of Spin Polarized Angle Resolved Photoemission and X-ray Magnetic Circular Dichroism, trying to find the effect of the magnetic coupling between the ferromagnetic substrate and organic molecular layer on the spin-dependent electronic properties at the interface.
