Currently our main interest is concentrated at controlling spins in adsorbed molecules by chemical and/or physical switches. We perform in-depth studies of various molecule-switch combinations in order to understand the mechanisms ruling the magnetic response. Density Functional Theory (DFT)+U calculations performed by our collaborators (see below) give a very important input to achieve this goal.
