Electron Glass Phase with Resilient Zhang-Rice Singlets in LiCu3O3

Rosario Scopelliti, László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Krunoslav Prsa, Simon Karl Moser, Paul Gregory Freeman, Jens Christian Johannsen, Gianmarco Gatti, Edoardo Martino

LiCu3O3 is an antiferromagnetic mixed valence cuprate where trilayers of edge -sharing Cu(II)O (3d9) are sandwiched in between planes of Cu(I) (3d10) ions, with Li stochastically substituting Cu(II). Angle resolved photoemission spectroscopy (ARPES) and de ...

The influence of the incommensurately modulated structure on the physical properties of Fe1.35Ge

László Forró, Alla Arakcheeva, Helmuth Berger, Philip Pattison, Krunoslav Prsa, Andrea Pisoni, Sergiy Katrych, Jacim Jacimovic

Single crystal growth by chemical vapour transport has resulted samples with Fe1.35Ge stoichiometry. Structural study has shown that the large number of vacancies introduces an incommensuately modulated structure. The electrical resistivity is in the 200 m ...

Singlet state formation and its impact on the magnetic structure in the tetramer system SeCuO3

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Helmuth Berger, Krunoslav Prsa, Peter Babkevich

We present an experimental investigation of the magnetic structure in a tetramer system SeCuO3 using neutron powder-diffraction and nuclear resonance techniques. We establish a commensurate antiferromagnetic ordering with a propagation vector k = (0, 0, 1) ...

Crystal Structure, Transport, and Magnetic Properties of an Ir6+ Compound Ba8Al2IrO14

László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Alla Arakcheeva, Lin Yang, Ana Akrap, Krunoslav Prsa, Sergiy Katrych, Bastien Dalla Piazza, Andrea Pisoni

The novel iridate Ba8Al2IrO14 was prepared as single crystals by self-flux method, thereby providing a rare example of an all-Ir(VI) compound that can be synthesized under ambient pressure conditions. The preparation of all-Ir6+ iridate without using tradi ...

Intrachain antiferromagnetic exchange in a 1D branched-chain built of two different copper(II) centres interlinked by end-on azido and phenoxo bridges: electron density map, electrochemical and magnetic properties

Henrik Moodysson Rønnow, Kurt Schenk, Philip Pattison, Krunoslav Prsa, Arash Alahgholipour Omrani, Noore Elahi Shaik

A 1D, end-on azido- and phenoxo-bridged, coordination polymer, Cu-2(mu-NAPPR)(mu(1,1)-N-3)(2) (1), (NAPPR(2-) = 1,3-bis(naphthylideneimino) propane dianion), was synthesized and characterized. The 1D branched-chain is built of two types of slightly di ...

Electric-Field-Induced Skyrmion Distortion and Giant Lattice Rotation in the Magnetoelectric Insulator Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Helmuth Berger, Ping Huang, Arash Alahgholipour Omrani, Jonathan White, Krunoslav Prsa

Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortexlike objects, display a magnetoelectric coupling and can be manipulated by externally applied electric (E) fields. Here, we explore the E-field coupling to the magne ...

Magnetic order in the 2D Heavy-Fermion system CePt2In7 studied by mu+SR

Marco Grioni, Kamil Sedlák, Martin Mansson, Krunoslav Prsa

The low-temperature microscopic magnetic properties of the quasi-2D heavy-fermion compound, CePt2In7 are investigated by using a positive muon-spin rotation and relaxation (mu+SR) technique. Clear evidence for the formation of a commensurate antiferromagne ...

Exploration of the helimagnetic and skyrmion lattice phase diagram in Cu2OSeO3 using magnetoelectric susceptibility

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Helmuth Berger, Krunoslav Prsa, Jonathan White, Arash Alahgholipour Omrani

Using superconducting quantum interference device magnetometry techniques, we have studied the change in magnetization versus applied ac electric field, i.e. the magnetoelectric (ME) susceptibility dM/dE, in the chiral-lattice ME insulator Cu2OSeO3. Measur ...

Lithium Diffusion & Magnetism in Battery Cathode Material LixNi1/3Co1/3Mn1/3O2

Martin Mansson, Kamil Sedlák, Krunoslav Prsa

We have studied low-temperature magnetic properties as well as high-temperature lithium ion diffusion in the battery cathode materials LixNi1/3Co1/3Mn1/1O2 by the use of muon spin rotation/relaxation. Our data reveal that the samples enter into a 2D spin-g ...

Temperature-dependent electron-phonon coupling in La_{2−x}Sr_{x}CuO_{4} probed by femtosecond x-ray diffraction

Majed Chergui, Henrik Moodysson Rønnow, Fabrizio Carbone, Paul Beaud, Krunoslav Prsa, Giulia Fulvia Mancini, Mathieu Julien Gino Cottet, Kazimierz Conder

The strength of the electron-phonon coupling parameter and its evolution throughout a solid's phase diagram often determines phenomena such as superconductivity, charge- and spin-density waves. Its experimental determination relies on the ability to distin ...
