CMOS/Magnetic Hybrid Architectures

The general purpose of spin-electronics is to take advantage of the spin of the electrons in addition to their electrical charge to conceive innovative electronic components. These components combine magnetic materials which are used as spin-polarizer or analyzer together with semiconductors or insulators. SPINTEC Laboratory works on the development of these components and their integration in innovative hybrid CMOS/magnetic architectures. We study in particular the use of Magnetic Tunnel Junctions (MTJ) for the design of Magnetic Random Access Memories (MAM), Magnetic FPGA (FPGA) and non-reprogrammable logical devices (transceivers, adders, decoders). The design of these hybrid architectures requires to develop electrical equivalent models of the magnetic elementary components (magnetic tunnel junctions, spin-valves, Hall crosses) compatible with SPICE-like simulators. Complete simulations of the hybrid devices are performed before experimental realization and testing.
