Modeling Ferro- and Antiferromagnetic Interactions in Metal-Organic Coordination Networks

Klaus Kern, Sebastian Stepanow, Tzu-Chun Tseng, Violetta Sessi, Alexander Langner, Nasiba Abdurakhmanova, Christopher Seiji Kley

Magnetization curves of two rectangular metalorganic coordination networks formed by the organic ligand TCNQ (7,7,8,8-tetracyanoquinodimethane) and two different (Mn and Ni) 3d transition metal atoms [M(3d)] show marked differences that are explained using ...

Complex trend of magnetic order in Fe clusters on 4d transition-metal surfaces. I. Experimental evidence and Monte Carlo simulations

Klaus Kern, Violetta Sessi

We demonstrate the occurrence of compensated spin configurations in Fe clusters and monolayers on Ru(0001) and Rh(111) by a combination of x-ray magnetic circular dichroism experiments, first-principles calculations, and Monte Carlo simulations. Our result ...

Superexchange-Mediated Ferromagnetic Coupling in Two-Dimensional Ni-TCNQ Networks on Metal Surfaces

Klaus Kern, Tzu-Chun Tseng, Violetta Sessi, Nasiba Abdurakhmanova, Christopher Seiji Kley

We investigate the magnetic coupling of Ni centers embedded in two-dimensional metal-coordination networks self-assembled from 7,7,8,8-tetracyanoquinodimethane (TCNQ) molecules on Ag(100) and Au (111) surfaces. X-ray magnetic circular dichroism measurement ...
