Magnetic anisotropy of Fe and Co ultrathin films deposited on Rh(111) and Pt(111) substrates: An experimental and first-principles investigation

Harald Brune, Stefano Rusponi, Pietro Gambardella, Markus Etzkorn, Anne Lehnert, Géraud Moulas

We report on a combined experimental and theoretical investigation of the magnetic anisotropy of Fe and Co ultrathin layers on strongly polarizable metal substrates. Monolayer (ML) films of Co and Fe on Rh(111) have been investigated in situ by x-ray magne ...

Effects of glass additions on the microstructure and dielectric properties of barium strontium titanate (BST) ceramics

Alexander Tagantsev

Commercial glass frits (lead borosilicate glasses) were employed as the sintering aids to reduce the sintering temperatures of BST ceramics. The effects of the glass content and the sintering temperature on the microstructures, dielectric properties and tu ...

Collective Magnetic Excitations in the Spin Ladder Sr14Cu24O41 Measured Using High-Resolution Resonant Inelastic X-Ray Scattering

Henrik Moodysson Rønnow, Thorsten Schmitt, Joël Mesot, Xi Wang

We investigate magnetic excitations in the spin-ladder compound Sr14Cu24O41 using high-resolution Cu L-3 edge resonant inelastic x-ray scattering (RIXS). Our findings demonstrate that RIXS couples to two-triplon collective excitations. In contrast to inela ...

Supramolecular control of the magnetic anisotropy in two-dimensional high-spin Fe arrays at a metal interface

Klaus Kern, Harald Brune, Magalí Alejandra Lingenfelder, Pietro Gambardella, Sebastian Stepanow, Sylvain Clair, Alexandre Dmitriev

Magnetic atoms at surfaces are a rich model system for solid-state magnetic bits exhibiting either classical(1,2) or quantum(3,4) behaviour. Individual atoms, however, are difficult to arrange in regular patterns(1-5). Moreover, their magnetic properties a ...

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 ...

Control of Ferromagnetism in a (Ga,Mn)As - Based Multiferroic System via a Ferroelectric Gate

Nava Setter, Igor Stolichnov, Harry Joseph Trodahl, Sebastian Riester

We report the implementation of a ferroelectric gate field effect transistor (FeFET) with a ferromagnetic (Ga,Mn)As conducting channel. The Curie temperature T-C in the channel is modulated by non-volatile poling of the gate. The ferroelectric state, and t ...

Magnetic and resonance properties of the two-dimensional S=1 compound Ni-5(TeO3)(4)Cl-2 with frustrated geometry

Helmuth Berger

The magnetic and magnetoresonance properties of a new single-crystal compound Ni-5(TeO3)(4)Cl-2 are studied. Measurements of the magnetization and magnetic susceptibility of the crystal in a wide temperature range (5-300 K) make it possible to conclude tha ...
