The main applications of those devices for computing will be reviewed\, including the realization of Ising machines based on probabili stic computing with p-bits and oscillatory dynamics.\nSpintronic technolog y takes advantage of the manipulation of the electron spin together with i ts charge. This technology potentially combines important characteristics such as ultralow power needs\, compactness (nanoscale size) and it is CMOS -compatible. Spintronics has different success stories such as the head re ad for magnetic hard drive and the recent spin-transfer-torque magnetic ra ndom access memories. The latter are realized with MTJs which are devices composed of two ferromagnets separated by a ultrathin isolating material. The resistance of this device depends on the relative orientation of the m agnetization of the two ferromagnets and in particular the configuration w here the magnetization are parallel or antiparallel can code the binary in formation. Together with memory developments\, which are already in the ma rket and integrated within the CMOS processes by main foundries (INTEL\, S AMSUNG\, GlobalFoundries)\, MTJs can be used for the development of auto-o scillators and very high efficient detectors. In detail\, I will show the applications of spintronic diodes based on MTJs for energy harvesting\, se nsors and RF detectors and what it is expected to achieve in the next thre e years for integration with CMOS-technology.\n\nThe latter part of the ta lk will focus on probabilistic computing which is one direction to impleme nt Ising Machines. Probabilistic computing is a computational paradigm usi ng probabilistic bits (p-bits)\, unit in the middle between standard bit a nd q-bits. I will show how to map hard combinatorial optimization problems (Max-Sat\, Max-Cut\, etc) into Ising machine and how to implement those i n spintronic technology. New direction in this field will present\, consid ering the concept of extended probabilistic variable such as p-dit and p-i nt.\n\nThis work was supported under the project number 101070287 — SWAN -on-chip — HORIZON-CL4-2021-DIGITAL-EMERGING-01\, the project PRIN 2020L WPKH7 funded by the Italian Ministry of University and Research and by the PETASPIN association (www.petaspin.com) and it has been also funded by Eu ropean Union (NextGeneration EU)\, through the MUR-PNRR project SAMOTHRACE (ECS00000022).\n\nAbout the speaker:\n\nGiovanni Finocchio received the P h.D. degree in advanced technologies in optoelectronic\, photonic and elec tromagnetic modeling from the University of Messina\, Italy\, in 2005.
