Description

Molecular materials have recently caught the attention of spintronics, and significant efforts are being made towards their integration in this field. One of their most attractive aspects for spintronic applications is the weakness of their spin scattering mechanisms, implying that the spin polarization of the carriers can be maintained for a very long time in these materials. Moreover, these materials might have tunable chemical properties, opening a way for the integration of synthetic chemistry into spintronic devices.

In this talk I shall focus on different spintronic devices based on molecular thin films. In the first part, I will show how bathocuproinemolecules act as a spacer in hybrid ferromagnetic/organic spin valves.

In the second part I will introduce a hot-electron tunnel transistor with C60 fullerene as a collector. In this device, hot-electron magnetoconductance values of up to 90% at room temperature have been recorded. Moreover, this device can operate as a solid-state spectroscopic tool for investigating the energy level alignment between molecules and metals.
