Low Temperature Ferromagnetism in Chemically Ordered FeRh Nanocrystals

Harald Brune, Stefano Rusponi, Sergio Vlaic, Alberto Cavallin, Jan Gui-Hyon Dreiser

In sharp contrast to previous studies on FeRh bulk, thin films, and nanoparticles, we report the persistence of ferromagnetic order down to 3 K for size-selected 3.3 nm diameter nanocrystals embedded into an amorphous carbon matrix. The annealed nanopartic ...

An Endohedral Single-Molecule Magnet with Long Relaxation Times: DySc_{2}N@C_{80}

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

The magnetism of DySc2N@C80 endofullerene was studied with X-ray magnetic circular dichroism (XMCD) and a magnetometer with a superconducting quantum interference device (SQUID) down to temperatures of 2 K and in fields up to 7 T. XMCD shows hysteresis of ...

X-ray Magnetic Circular Dichroism (XMCD) Study of a Methoxide-Bridged Dy^III-Cr^III Cluster Obtained by Fluoride Abstraction from cis-[Cr^III F_2 (phen)_2]^+

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser

An isostructural series of dinuclear chromium(III)-lanthanide(III) clusters is formed by fluoride abstraction of cis-CrF2(phen)(2) by Ln(3+) resulting in LnF(3) and methoxide-bridged Cr-Ln clusters (Ln = Nd (1), Tb (2), Dy (3)) of formula [Cr-III(phen ...

X-Treme beamline at SLS: X-ray magnetic circular and linear dichroism at high field and low temperature

Harald Brune, Stefano Rusponi, Thomas Schmidt, Jan Gui-Hyon Dreiser

X-Treme is a soft X-ray beamline recently built in the Swiss Light Source at the Paul Scherrer Institut in collaboration with Ecole Polytechnique Federale de Lausanne. The beamline is dedicated to polarization-dependent X-ray absorption spectroscopy at hig ...
