Abstract
The main goal of this project is the exploration of a new class of two dimensional materials, formed by doping semiconducting transition metal dichalcogenides, such as MoS2, with magnetic atoms such as Gd and Fe, leading a hybrid material that can be used in spintronic devices.
This project brings together researchers from 2 Portuguese institutions, INL and U. Minho, with UT Austin researchers from the Department of Physics to undertake the synthesis, characterization, magnetic measurements and modelling both of one of the paradigmatic layered semiconductors, MoS2 , doped with a small fraction (less than 10%) of magnetic atoms Fe and Gd. This will be accomplished both for bulk samples and their atomically thin counterparts, obtained by exfoliation. The systems so obtained will
be analogous to standard diluted magnetic semiconductor (DMS), and are expected to order ferromagnetically at low temperatures. The fabrication of two dimensional crystal with magnetic order could permit, further down the road, its integration in the so called Van der Waals structures, multilayers of different 2D materials, to yield functional devices such as spin valves.
