Topological Engineering of a Frustrated Antiferromagnetic Triradical in Aza-Triangulene Architectures
Francisco Romero-Lara, Manuel Vilas-Varela, Ricardo Ortiz +19
Open-shell nanographenes provide a versatile platform to host unconventional magnetic states within their π-conjugated networks. Particularly appealing are graphene architectures t…
Topological edge states in a double isomeric Class-II oligo(indenoindene)
Ricardo Ortiz
I report the theoretical prediction of non-trivial physics in a one dimensional multiradical system consisting in fused six and five membered -conjugated carbon rings, known as…
Organic altermagnets based in two-dimensional nanographene frameworks
Ricardo Ortiz, Karol StrutyÅski, Manuel Melle-Franco
Altermagnetism stands as a third type of collinear magnetic order, whose band structure combines a net zero magnetization with a non-relativistic spin-splitting caused by a broken…
On-surface Synthesis of a Ferromagnetic Molecular Spin Trimer
Alessio Vegliante, Manuel Vilas-Varela, Ricardo Ortiz +12
Triangulenes are prototypical examples of open-shell nanographenes. Their magnetic properties, arising from the presence of unpaired electrons, can be extensively tuned by mod…
A Route Toward the On-Surface Synthesis of Organic Ferromagnetic Quantum Spin Chains
Fabian Paschke, Ricardo Ortiz, Shantanu Mishra +5
Engineering sublattice imbalance is an intuitive way to induce high-spin ground states in bipartite polycyclic conjugated hydrocarbons (PCHs). Such high-spin molecules can be emplo…
