Expérimental
The purpose of this internship or thesis is the characterization of the surface magnetization of samples by collision with highly charged ions. The x-ray emission that accompaign the collision depends on the alignment of the spins of the captured electrons by the ion providing information on the magnetic phase of the sample surface. A proof of principal experiment has been recently performed that demonstrates the sensitivity of x-ray emission to the ferro-/paramagnetic phase phases of a nickel sample surface. The proposed internship/Ph.D. consists of continuing this stimulating new research topic. The following steps are: 1) to extend such a study to other materials like LaSrMnO (ferro-/paramagnetic transition) and FeRh (antiferro-/ferromagnetic transition), 2) to implement coincidence detection between the x rays and the ion charge state after the collision and 3) to implement high-resolution x-ray spectroscopy
