• Professor Marco Affronte

    University of Modena, Italy

    Marco suggested to us to use Cr7Ni rings in quantum information processing, thus inspiring one of our most active areas of research. His group has carried out heat capacity and torque magnetometry measurements. At the moment our major collaboration involves attaching molecular magnets to surfaces. Our joint paper in ACS Nano is the first to report an ordered monolayer of polymetallic cage complexes on a surface.

    Our collaboration with Ames Laboratory started through discussions with Marshall Luban about using theory developed in his group to model magnetic behavior. We have continued this collaboration, both with Marshall and his former PhD student Larry Engelhardt (see above), particularly using quantum Monte Carlo methods to fit data on large systems. Later we began collaborating with Ruslan, using a fascinating technique called transmission diode oscillators to measure magnetic behavior at very low temperature. This technique had not been applied previously to molecular magnets, and it seems to provide information on excited state crossings that cannot be obtained by other means. Our collaboration with Yuji uses his expertise in solid state NMR spectroscopy.
