This Ph.D or postdoctoral position is opened in the frame of a collaborative project funded by the French government on orbital electronics named OXIMOR, as part of the PEPR “SPIN” .

Our team investigates the generation of spin and orbital electronic currents for spin–orbit torques in solid-state devices made of light metals, metallic ferromagnets and/or magnetic insulators. In the electrical excitation of magnetization dynamics by torques, the different channels related to spin dynamics and orbital dynamics need to be disentangled, which we want to accomplish by experiments involving magnetic transport measurements and microwave spectroscopy of magnetization dynamics. The Ph.D./postdoc will focus on the electronic measurement of metallic and magnetic oxide heterostructures subjected to microwaves, and will image the displacement of magnetic textures by currents, to quantify their efficiency in the generation of orbital currents and torques. The Ph.D./postdoc will actively participate to the collective dynamics of the national project OXIMOR together with our partner labs specialized in theory, materials and devices, in order to further understand the physics involved in orbitronics phenomena. Our approach will rely on the realization of new measurement procedures combining several kinds of electronic and microwave instrumentation.

The core of this Ph.D. work will be to explore the fundamental coupling mechanisms of ferrimagnetic and antiferromagnetic magnons in the sub-THz to THz frequency range. The project will span several classes of magnetic oxides to be grown in Grenoble as part of this Ph.D. work, and also obtained through external collaborations. You will benefit from the holistic knowhow in Grenoble covering from materials and spintronics to high fields and THz spectroscopies, in NEEL (W. Legrand, L. Ranno), SPINTEC (V. Baltz and U. Ebels) and LNCMI (A.-L. Barra), and from national and international collaborations. You will work with state-of-the-art techniques for oxide synthesis, cleanroom fabrication, characterization at the nanoscale under cryogenic temperatures, as well as experiments under strong magnetic fields (15 T) and large frequencies (600 GHz) developed in LNCMI. The Ph.D. thesis will be officially directed by the NEEL team (W. Legrand, L. Ranno), and is a collaborative project granted by UGA to the 3 teams at NEEL, SPINTEC and LNCMI, thus providing comprehensive guidance on this multi-faceted research topic.
