Magnetic phase diagram of Ca-substituted EuFe2As2
The simultaneous presence of an Fe-related spin-density wave and the antiferromagnetic order of Eu-2(+) moments ranks EuFe2As2 among the most interesting parent compounds of iron-based pnictide superconductors. Here we explore the consequences of the dilut ...
AMER PHYSICAL SOC2018Magnetic properties of surface-adsorbed single rare earth atoms, molecules, and atomic scale clusters
This thesis presents combined experimental and theoretical investigations of nanoscale, surface-supported magnets based on rare earths (RE) to understand and control the magnetic properties down to the scale of single atoms. We present the effects of adato ...
EPFL2017Reading and writing single-atom magnets
The single-atom bit represents the ultimate limit of the classical approach to high-density magnetic storage media. So far, the smallest individually addressable bistable magnetic bits have consisted of 3-12 atoms(1-3). Long magnetic relaxation times have ...
Nature Publishing Group2017High-Temperature Ferrimagnetism with Large Coercivity and Exchange Bias in the Partially Ordered 3d/5d Hexagonal Perovskite Ba2Fe1.12Os0.88O6
Double perovskite oxides A(2)BB'O-6 combining 3d and 4d or 5d transition metal ions at the B and B' sites feature a variety of magnetic and magneto-electric properties. Targeting Ba2FeOsO6, we synthesized powder samples of nonstoichiometric Ba2Fe1.12Os0.88 ...
American Chemical Society2017Mining of rare earth metals from hydro mineral resources in Siberia: trends and prospects
Siberian scientists showed by their scientific investigations that brines of Siberian Platform are a very important hydro mineral resource for economical development of the East Russia. Prospects for the integrated mining of the hydromineral resources in R ...
A World Resources Forum Production, PSI2017Spin and orbital disordering by hole doping in Pr1-xCaxVO3
High-resolution powder x-ray diffraction and single-crystal neutron diffraction were used to investigate the crystal structure and magnetic ordering of the compound Pr1-xCax VO3 (0
Amer Physical Soc2016Two-dimensional metal-organic networks as templates for the self-assembly of atom and cluster arrays
This thesis presents a study of the use of two-dimensional metal-organic systems as templates for the organization of metal atoms and clusters on surfaces. We start with a systematic characterization of the metal-organic porous networks formed on Cu(111) b ...
EPFL2016Magnetic and Magnetoelectric Measurements on Ba2CoGe2O7
Multiferroic materials show, in a single phase, at least two ferroic properties. The latter are are (anti-)ferroelectricity, (anti-)ferromagnetism or (anti-)ferroelasticity. Interesting applications can use the properties of multiferroics, especially with ...
2016Exchange Interaction of Strongly Anisotropic Tripodal Erbium Single-Ion Magnets with Metallic Surfaces
Harald Brune, Stefano Rusponi, Christian Wäckerlin, Jan Gui-Hyon Dreiser, Fabio Donati, Aparajita Singha
We present a comprehensive study of Er(trensal) single-ion magnets deposited in ultrahigh vacuum onto metallic surfaces. X-ray photoelectron spectroscopy reveals that the molecular structure is preserved after sublimation, and that the molecules are physis ...
Amer Chemical Soc2014Intracorporeal anchoring and guiding system with permanent magnet force modulation
Magnetic manipulation of objects within the body is a growing field of research since the second half of the last century. Therapeutic and diagnostic capabilities offered by such technology are extended with the clinical need to make procedures less invasi ...
