Radical-Induced Changes in Transition Metal Interfacial Magnetic Properties: A Blatter Derivative on Polycrystalline Cobalt

Autor: Nowik-Boltyk, Ewa Malgorzata, Junghoefer, Tobias, Giangrisostomi, Erika, Ovsyannikov, Ruslan, Shu, Chan, Rajca, Andrzej, Droghetti, Andrea, Casu, M. Benedetta

In this work, we study the cobalt radical interface obtained by depositing a monolayer of a derivative of the Blatter radical on polycrystalline cobalt. By examining the occupied and unoccupied states at the interface, using soft X-ray techniques, an

Organic-inorganic halide perovskites have been intensively re-investigated due to their applications, yet the opto-electronic function of the organic cation remains unclear. Through organic-selective resonant Auger electron spectroscopy measurements

Overcoming the challenges in controlled thermal deposition of organic diradicals

Autor: Junghoefer, Tobias, Gallagher, Nolan M., Kolanji, Kubandiran, Giangrisostomi, Erika, Ovsyannikov, Ruslan, Chassé, Thomas, Baumgarten, Martin, Rajca, Andrzej, Calzolari, Arrigo, Casu, Maria Benedetta

We have demonstrated that it is possible to evaporate diradicals in a controlled environment obtaining thin films in which the diradical character is preserved. However, evaporation represents a challenge. The presence of two radical sites makes the

Stability of radical-functionalized gold surfaces by self-assembly and on-surface chemistry

Autor: Junghoefer, Tobias, Nowik-Boltyk, Ewa Malgorzata, de Sousa, J. Alejandro, Giangrisostomi, Erika, Ovsyannikov, Ruslan, Chassé, Thomas, Veciana, Jaume, Mas-Torrent, Marta, Rovira, Concepció, Crivillers, Núria, Casu, Maria Benedetta

We have investigated the radical functionalization of gold surfaces with a derivative of the perchlorotriphenylmethyl (PTM) radical, using two methods: by chemisorption from the radical solution and by on surface chemical derivatization from a precur

Magnetic ordering in metal-free radical thin films

Autor: Junghoefer, Tobias, Baev, Ivan, Glaser, Mathias, Ciccullo, Francesca, Giangrisostomi, Erika, Ovsyannikov, Ruslan, Kielgast, Fridtjof, Nissen, Matz, Schwarz, Julius, Gallagher, Nolan M., Rajca, Andrzej, Martins, Michael, Calzolari, Arrigo, Casu, Maria Benedetta

Molecular systems are materials that intersect with many different promising fields such as organic/molecular electronics and spintronics, organic magnetism and quantum computing1-7. Particularly, magnetism in organic materials is very intriguing: th
