Assembly of molecular nanomagnets into nanogap electrodes by dielectrophoresis.

: We investigate the assembly of Prussian blue and Cs-Co-Cr Prussian blue analogue molecular nanomagnets into nano-patterned electrodes. Pd or Au gaps - 7-50 nm were fabricated on a SiO2/Si substrate using standard electron beam lithography and lift-off. Nanomagnets were positioned between the gaps via AC dielectrophoresis (DEP). At room temperature, the Cs-Co-Cr Prussian blue analogue nanoparticles exhibited negligible current whereas junction with Prussian blue nanoparticles exhibited - 30 pA at - 1 V.
