Context: In the frame of the Chirex project of the PEPR Spin, Spintec laboratory is opening a postdoctoral researcher position. The candidate will work on ultrathin magnetic heterostructures hosting skyrmions and deposited by magnetron sputtering at Spintec, and will use them to explore the combination of gate voltage and ultrafast laser pulses to control skyrmion stability, nucleation, annihilation and motion. The project is a collaboration with the team of Prof. S. Mangin at Institut Jean Lamour (IJL) in Nancy (France) where the candidate will use ultrafast laser pulses for skyrmion control.

Position: The work includes (i) optimizing the growth conditions of heterostructures to transfer our optimized stack from Si wafers to glass substrates, for laser pulses application, (ii) desining the devices and performing the process of the samples in the clean room, accessible at Spintec, for gate voltage application and for further laser pulse application, (iii) characterizing magnetic properties using magneto-optical Kerr effect microscopy and (iv) performing measurements of skyrmion nucleation, annihilation and current-induced motion under the combination of gate voltage and laser pulses at IJL.

The candidate must hold a Ph.D. in physics, with a good knowledge in magnetism and spintronics and familiarities with gate voltage control or ultrafast laser magnetization control. A previous experience in clean room will be highly appreciated. The successful candidate will join the « Magnetic sensor» team of Spintec and a consortium of laboratories that are leaders in the control of skyrmions with gate voltage [1] and the control of magnetization by ultrafast laser pulses [2].
