Strong antiferromagnetic exchange between manganese phthalocyanine and ferromagnetic europium oxide

Stefano Rusponi, Jan Gui-Hyon Dreiser, Fabio Donati, Aparajita Singha, Romana Baltic

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 involvin ...

Sound Isolation and Giant Linear Nonreciprocity in a Compact Acoustic Circulator

Romain Christophe Rémy Fleury

Acoustic isolation and nonreciprocal sound transmission are highly desirable in many practical scenarios. They may be realized with nonlinear or magneto-acoustic effects, but only at the price of high power levels and impractically large volumes. In contra ...

Tracking Temperature-Dependent Relaxation Times of Ferritin Nanomagnets with a Wideband Quantum Spectrometer

Klaus Kern, Markus Ternes

We demonstrate the tracking of the spin dynamics of ensemble and individual magnetic ferritin proteins from cryogenic up to room temperature using the nitrogen-vacancy color center in diamond as a magnetic sensor. We employ different detection protocols to ...

Spin-Nematic Interaction in the Multiferroic Compound Ba2CoGe2O7

Martin Mansson

We demonstrate the existence of the spin-nematic interactions in an easy-plane type antiferromagnet Ba2CoGe2O7 by exploring the magnetic anisotropy and spin dynamics. The combination of neutron scattering and magnetic susceptibility measurements reveals th ...

Magnetization reversal mechanism of ramified and compact Co islands on Pt(111)

Harald Brune, Stefano Rusponi, Donat Fabian Natterer, Anne Lehnert, Alberto Cavallin, Géraud Moulas

We report on the magnetization reversal mechanism of Co islands on Pt(111) as a function of their size and shape. We measure the zero-field susceptibility chi(T) and low-temperature magnetization curves M(H) with in situ magneto-optical Kerr effect. Togeth ...

Cluster-size dependent internal dynamics and magnetic anisotropy of Ho ions in HoM2N@C-80 and Ho2MN@C-80 families (M = Sc, Lu, Y)

Yi Zhang, Jan Gui-Hyon Dreiser

The paramagnetic NMR study of HoM2N@C-80-I-h and Ho2MN@C-80-I-h nitride cluster fullerenes (M = Sc, Lu, Y) reveals strong dependence of Ho-induced paramagnetic shifts (delta(para)) in C-13 NMR spectra on the size of the diamagnetic metal in the cluster. In ...

Single-Molecule-Magnet Behavior in Mononuclear Homoleptic Tetrahedral Uranium(III) Complexes

Marinella Mazzanti, Lucile Sylvie Danielle Chatelain

The magnetic properties of the two uranium coordination compounds, [K(18c6)][U(OSi-((OBu)-Bu-t)(3))(4)] and [K(18c6)][U(N(SiMe3)(2))(4)], both presenting the U-III ion in similar pseudotetrahedral coordination environments but with different O- or N-donor ...

Magnetism of Ho and Er Atoms on Close-Packed Metal Surfaces

Harald Brune, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Pietro Gambardella, Fabio Donati, Aparajita Singha

We investigated the magnetic properties of individual Ho atoms adsorbed on the (111) surface of Pt, which have been recently claimed to display single ion magnetic behavior. By combining x-ray absorption spectroscopy and magnetic dichroism measurements wit ...
