High-Field Magnetization of the Distorted Spin Frustration System Ni-5(TeO3)(4)Br-2

We performed high-field magnetization measurements, M(H), on the Ni-5(TeO3)(4)Br-2 by using a pulse magnet. The Ni2+ ions (S = 1) of this compound form a two dimensional distorted spin frustrated system (distorted kagome lattice), and undergo a Neel transi ...

Strong ferroelectric domain-wall pinning in BiFeO3 ceramics

Nava Setter, Dragan Damjanovic, Marija Kosec

We have studied the polarization-electric-field hysteresis, the dielectric permittivity dispersion, the piezoelectric properties, the electric-field-induced strain, and the interrelations between these properties for bismuth ferrite (BiFeO3) ceramics. The ...

Magnetic phase diagram of the multiferroic FeTe2O5Br

Helmuth Berger

The low-temperature magnetic phase diagram of the multiferroic system FeTe2O5Br down to 300 mK and up to 9 T is presented. Short-range magnetic correlations within the crystal layers start to develop already at similar to 50 K, i.e., far above T-N1 similar ...

Spectroscopic Studies on Semiconducting Interfaces with Giant Spin Splitting

Emmanouil Frantzeskakis

The application of an external magnetic field can lift the spin degeneracy of electronic states through its interaction with the electronic magnetic moment. A closely-related phenomenon is the Rashba-Bychkov (RB) effect where symmetry breaking at surfaces ...

Modeling and Characterization of Coated Conductors Applied to the Design of Superconducting Fault Current Limiters

François Roy

The Superconducting Fault Current Limiter (SFCL) appears to be a device of great interest to efficiently build the electrical grid of tomorrow. With the recent progress made by the superconducting wires manufacturers, there are needs coming from the indust ...

Spatially Extended Kondo State in Magnetic Molecules Induced by Interfacial Charge Transfer

Nicola Marzari

An extensive redistribution of spin density in TBrPP-Co molecules adsorbed on a Cu(111) surface is investigated by monitoring Kondo resonances at different locations on single molecules. Remarkably, the width of the Kondo resonance is found to be much larg ...

Pinning and Depinning of the Polarization of Exciton-Polariton Condensates at Room Temperature

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Jacques Levrat, Marlene Glauser

A room temperature polariton condensate realized in a microcavity with embedded GaN quantum wells emits linearly polarized light at threshold with the plane of polarization pinned to one of the crystallographic axes. With increasing pumping power, a depinn ...

Exciton-polariton spin switches

Romuald Houdré, Timothy Chi Hin Liew

Integrated switching devices comprise the building blocks of ultrafast optical signal processing(1,2). As the next stage following intensity switching(1,3,4), circular polarization switches(5-9) are attracting considerable interest because of their applica ...

Reversible assembly of magnetized particles: Application to water-borne pathogen enumeration

Reversible assembly of magnetized particles and cells has been proposed and implemented. The approach is based on magnetized particles or magnetically labeled cell immobilization in an array of individual particle/cell for optical counting. The device has ...

High resolution in situ magneto-optic Kerr effect and scanning tunneling microscopy setup with all optical components in UHV

Harald Brune, Stefano Rusponi, Philipp Buluschek, Nicolas Weiss, Anne Lehnert, Matthias Treier

A surface magneto-optic Kerr effect (MOKE) setup fully integrated in an ultrahigh vacuum chamber is presented. The system has been designed to combine in situ MOKE and scanning tunneling microscopy. Magnetic fields up to 0.3 T can be applied at any angle i ...
