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, Andrea Pisoni, Sergiy Katrych, Bastien Dalla Piazza, Jacim Jacimovic

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 ...

Note: Versatile sample stick for neutron scattering experiments in high electric fields

Henrik Moodysson Rønnow, Jonathan White, Krunoslav Prsa

We present a versatile high voltage sample stick that fits into all cryomagnets and standard cryostats at the Swiss Spallation Neutron Source, Paul Scherrer Institut, and which provides a low effort route to neutron scattering experiments that combine elec ...

Chirality of structure and magnetism in the magnetoelectric compound Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Jonathan White, Krunoslav Prsa, Ping Huang

Small-angle diffraction of polarized neutrons and resonant contribution to diffraction of synchrotron radiation have been applied to prove chirality of the crystal and magnetic structures of the magnetoelectric insulator Cu2OSeO3. Similarly to other chiral ...

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

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

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 ...

Critical scaling in the cubic helimagnet Cu2OSeO3

Henrik Moodysson Rønnow, Ivica Zivkovic, Helmuth Berger, Jonathan White, Krunoslav Prsa

We present a detailed ac susceptibility investigation of the fluctuation regime in the insulating cubic helimagnet Cu2OSeO3. For magnetic fields mu H-0 >= 200 mT, and over a wide temperature (T) range, the system behaves according to the scaling relations ...

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

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Helmuth Berger, Jonathan White, Krunoslav Prsa, 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 ...
