The talk entitled " All-optical switching in FeCoB/Ta/[Tb/Co]N electrodes for the development of ultrafast magnetic tunnel junctions" will be presented at the Advances in Magnetics conference hosted by the IEEE on June 13-16th, 2021-
The 2021 Around-the-Clock Around-the-Globe Magnetics Conference (AtC-AtG) is a 24-hour non-stop virtual conference with speakers from all over the world passing the baton to each other. Join, interact, or take a break at any time – for free. The contributed talks will be given by students and post-doctoral researchers only and invited talks by senior scientists.
In the frame of the forthcoming presidential and congress general elections in Peru next April 11th, I was invited as a panelist to forrmulate questions to the candidates to the congress. The questions, that aimed to discuss the strengths and weaknesses of the institutions dedicated to science, technology and innovation allowed to hear the support and proposals of the politicians for the next political period. This interview hosted by Cientificos.pe is one of several interviews during the two weeks before the elections.
We reported atomistic spin simulations of all-optical switching in multilayered structures alternating n monolayers of Tb and m monolayers of Co. By using a two temperature model, we numerically calculate the thermal variation of the magnetization of each sublattice as well as the magnetization dynamics of [Tbn/Com] multilayers upon incidence of a single laser pulse. In particular, the condition to observe thermally-induced magnetization switching is investigated upon varying systematically both the composition of the sample (n,m) and the laser fluence. The reversal mechanism is mediated by the residual magnetization of the Tb lattice while the Co is fully demagnetized in agreement with the models developed for
ferrimagnetic alloys. The intermixing at the Tb/Co interfaces appears to be a promising way to reduce the stochasticity. These results predict for the first time the possibility of TIMS in [Tb/Co] multilayers and suggest the occurrence of sub-picosecond magnetization reversal using single laser pulses.

A contributed talk entitled "Manipulation of spin currents in synthetic antiferromagnets" will be share at the Peruvian Meeting of Physics. This year the meeting will be host by the Science Faculty of the Engineering National University of Peru to commemorate its 60 Anniversary. Congratulations to my Alma Mater and looking forward to see you there!

Since July 1st I joined Magnetic Resonance Division of Bariloche Atomic Center as a Junior Researcher
Looking forward to open new research lines with former colleagues
New publication in IOP Nanotechnology. Our work propose the integration of ITO as a transparent conducting electrode for MTJs in integrated spintronic – photonic circuits.
