Strong antiferromagnetic exchange between manganese phthalocyanine and ferromagnetic europium oxide.

Chemical communications (Cambridge, England)

Wäckerlin C, Donati F, Singha A, Baltic R, Uldry AC, Delley B, Rusponi S, Dreiser J.
PMID: 26171839
Chem Commun (Camb). 2015 Aug 21;51(65):12958-61. doi: 10.1039/c5cc01823d.

We report on the antiferromagnetic exchange coupling between a submonolayer of Mn(II)-phthalocyanine molecules and a ferromagnetic Eu(II)-oxide thin film. The exchange energy is larger by nearly two orders of magnitude compared to previous studies involving oxidic substrates.

ACS Nano. 2016 Feb 23;10(2):2887-92. doi: 10.1021/acsnano.5b08178. Epub 2016 Feb 08.

We have studied Er(trensal) single-ion magnets adsorbed on graphene/Ru(0001), on graphene/Ir(111), and on bare Ru(0001) by scanning tunneling microscopy and X-ray absorption spectroscopy. On graphene, the molecules self-assemble into dense and well-ordered islands with their magnetic easy axes perpendicular...

Nano letters

Tchoulfian P, Donatini F, Levy F, Dussaigne A, Ferret P, Pernot J.
PMID: 24837761
Nano Lett. 2014 Jun 11;14(6):3491-8. doi: 10.1021/nl5010493. Epub 2014 May 29.

While core-shell wire-based devices offer a promising path toward improved optoelectronic applications, their development is hampered by the present uncertainty about essential semiconductor properties along the three-dimensional (3D) buried p-n junction. Thanks to a cross-sectional approach, scanning electron beam...

INTRODUCTION: Bleeding from pancreatic pseudocyst's rupture into adjacent organs is a rare, but potentially fatal, complication of chronic pancreatitis requiring quick management. Timing of the rupture is unpredictable; early diagnosis and correct management is essential in preventing the bleeding.CASE...
