Magnetic Molecules and Hybrid Materials for Molecular Spintronics Spin-based electronics is one of the emerging branches in today’s nanotechnology and the most active area within nanomagnetism. So far spintronics has been based on conventional materials like inorganic metals and semiconductors. Still, molecular electronics emerged several decades ago as a promising possibility to complement or even to replace conventional inorganic electronics when it goes nano. In this context, a natural evolution of molecular electronics is that of using magnetic molecules, as well as molecule-based materials, as components of new spintronic systems [1]. In this talk the major trends in this area will be presented, namely the development of spintronic structures incorporating molecular components, and the evolution towards single-molecule spintronics. I will focus on the design of new classes of magnetic molecular materials and magnetic molecules which, conveniently nanostructured, can be of interest in molecular spintronics, quantum-computing and, in general, nanomagnetism. As magnetic molecular materials, I will focus on those exhibiting multifunctional properties, in particular those in which magnetism co-exist with electric conductivity. As magnetic molecules, I will focus on inorganic magnetic molecules based on metal-oxide clusters (polyoxometalates). The chemical stability, together with the structural and electronic versatilities of polyoxometalates, will allow us to organize and address these molecules on metal surfaces. On the other hand, the use of these molecular metal-oxides as qubits in quantum computing will be discussed [2]. [1] J. Camarero, E.
