  • Ammonia Coordination Introducing a Magnetic Moment in an On‐Surface Low‐Spin Porphyrin 
    Wackerlin, Christian; Tarafder, Kartick; Girovsky, Jan; Nowakowski, Jan; Hahlen, Tatjana; Shchyrba, Aneliia; Siewert, Dorota; Kleibert, Armin; Nolting, Frithjof; Oppeneer, Peter M.; Jung, Thomas A.; BALLAV, NIRMALYA (Wiley, 2013-04)
    The molecular spin state of NiII porphyrin, supported on a ferromagnetic Co surface, can be reversibly switched between spin‐off (S=0) and spin‐on (S=1) states upon coordination and decoordination of the gaseous ligand ...
  • Two‐Dimensional Supramolecular Electron Spin Arrays (Adv. Mater. 17/2013) 
    Wackerlin, Christian; Nowakowski, Jan; Liu, Shi-Xia; Jaggi, Michael; Siewert, Dorota; Girovsky, Jan; Shchyrba, Aneliia; Hählen, Tatjana; Kleibert, Armin; Oppeneer, Peter M.; Nolting, Frithjof; Decurtins, Silvio; Jung, Thomas A.; BALLAV, NIRMALYA (Wiley, 2013-05)
    Addressable arrangements of spins at the molecular scale provide novel and exciting possibilities towards future spintronic applications. On page 2404, Nirmalya Ballav, Christian Wäckerlin, and co‐workers employ a bottom‐up ...
  • Emergence of On-Surface Magnetochemistry 
    BALLAV, NIRMALYA; Wackerlin, Christian; Siewert, Dorota; Oppeneer, Peter M.; Jung, Thomas A. (American Chemical Society, 2013-07)
    The control of exchange coupling across the molecule–substrate interface is a key feature in molecular spintronics. This Perspective reviews the emerging field of on-surface magnetochemistry, where coordination chemistry ...
  • Magnetic exchange coupling of a synthetic Co(II)-complex to a ferromagnetic Ni substrate 
    Wackerlin, Christian; Maldonado, Pabl; Arnold, Lena; Shchyrba, Aneliia; Girovsky, Jan; Nowakowski, Jan; Ali, Md. Ehesan; Hahlen, Tatjana; Baljozovic, Milos; Siewert, Dorota; Kleibert,; Klaus Mullen; Oppeneer, Peter M.; Jung, Thomas A.; BALLAV, NIRMALYA (Royal Society of Chemistry, 2013-09)
    On-surface assembly of a spin-bearing and non-aromatic porphyrin-related synthetic Co(II)-complex on a ferromagnetic Ni thin film substrate and subsequent magnetic exchange interaction across the interface were studied by ...
  • Investigating magneto-chemical interactions at molecule substrate interfaces by X-ray photo-emission electron microscopy 
    Irovsky, Jan; Buzzi, Michele; Wackerlin, Christian; Siewert, Dorota; Nowakowski, Jan; Oppeneer, Peter M.; Nolting, Frithjof; Jung, Thomas A.; Kleibert, Armin; BALLAV, NIRMALYA (Royal Society of Chemistry, 2013-12)
    The magneto-chemical interaction of spin-bearing molecules with substrates is interesting from a coordination chemistry point of view and relevant for spintronics. Unprecedented insight is provided by X-ray photo-emission ...
  • Antiferromagnetic coupling of Cr-porphyrin to a bare Co substrate 
    Girovsky, Jan; Tarafder, Kartick; Wackerlin, Christian; Nowakowski, Jan; Siewert, Dorota; Hahlen, Tatjana; Wckerlin, Aneliia; Kleibert, Armin; BALLAV, NIRMALYA; Jung, Thomas A.; Oppeneer, Peter M. (American Physical Society, 2014-12)
    We report the discovery of an antiferromagnetic coupling of the magnetic moment of chromium(II) tetraphenyl-porphyrin (CrTPP) molecules to the magnetization of the clean ferromagnetic Co(001) substrate. We assign this ...
  • Possible Room-Temperature Ferromagnetism in Self-Assembled Ensembles of Paramagnetic and Diamagnetic Molecular Semiconductors 
    DHARA, BARUN; Tarafder, Kartick; JHA, PLAWAN KUMAR; Panja, Soumendra Nath; NAIR, SUNIL; Oppeneer, Peter M.; BALLAV, NIRMALYA (American Chemical Society, 2016-12)
    Owing to long spin-relaxation time and chemically customizable physical properties, molecule-based semiconductor materials like metal-phthalocyanines offer promising alternatives to conventional dilute magnetic ...
  • Long-range ferrimagnetic order in a two-dimensional supramolecular Kondo lattice 
    Girovsky, Jan; Nowakowski, Jan; Ali, Md. Ehesan; Baljozovic, Milos; Rossmann, Harald R.; Nijs, Thomas; Aeby, Elise A.; Nowakowska, Sylwia; Siewert, Dorota; Srivastava, Gitika; Wackerlin, Christian; Dreiser, Jan; Decurtins, Silvio; Liu, Shi-Xia; Oppeneer, Peter M.; Jung, Thomas A.; BALLAV, NIRMALYA (Nature Publishing Group, 2017-05)
    Realization of long-range magnetic order in surface-supported two-dimensional systems has been challenging, mainly due to the competition between fundamental magnetic interactions as the short-range Kondo effect and ...
