Magneto-optical response of the magnetic semiconductors EuCd2X2 (X =P, As, Sb)

Jan Hugo Dil, Ivica Zivkovic, Michele Puppin, Fei Guo

In this study, we identify EuCd2X2 (for X = P, As, Sb) as a series of magnetic semiconductors. We examine how the band gap of the series responds to X changing from phosphorus (P), to arsenic (As), and finally antimony (Sb). We characterize the samples usi ...

High-Temperature Phase Transitions Preceding the Decomposition of Mixed Valence Aluminum Titanate Pseudobrookite

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Yong Liu, Davor Tolj

Dark blue single crystals of Al1.753+Ti1.04+Ti0.253+O5 were grown with a novel synthesis method based on the reaction of a Ti3+/Ti4+-containing langbeinite melt and porous alpha-alumina crucible. The obtained needles crystallize in the pseudobrookite struc ...

Spectroscopic signatures and origin of hidden order in Ba2MgReO6

Henrik Moodysson Rønnow, Oleg Yazyev, Ivica Zivkovic, Jana Pásztorová, Davor Tolj

Clarifying the underlying mechanisms that govern ordering transitions in condensed matter systems is crucial for comprehending emergent properties and phenomena. While transitions are often classified as electronically driven or lattice-driven, we present ...

Siloxide tripodal ligands as a scaffold for stabilizing lanthanides in the +4 oxidation state

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Fang-Che Hsueh

Synthetic strategies to isolate molecular complexes of lanthanides, other than cerium, in the +4 oxidation state remain elusive, with only four complexes of Tb(iv) isolated so far. Herein, we present a new approach for the stabilization of Tb(iv) using a s ...

A trinuclear metallasilsesquioxane of uranium(III)

Rosario Scopelliti, Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic, Nadir Jori

The silsesquioxane ligand (Bu-i)(7)Si7O9(OH)(3) ((POSSH3)-P-iBu) is revealed as an attractive system for the assembly of robust polynuclear complexes of uranium(III) and allowed the isolation of the first example of a trinuclear U(III) complex ([U-3((POSS) ...

Reinvestigation of the Crystal Structure and Magnetic Properties of M(vo)2(po4)24h2o and Ni0.5(vo)2(po4)21.5h2o (m = Ni2+, Co2+) Compounds

Ivica Zivkovic

In today's technology, the need for data-and energy storage devices with a high efficiency and capacity, as well as a high writing speed for the former is ever increasing. For such applications, materials with a magnetic nature, i.e. Ferro-, Ferri-and Anti ...

Synthesis, structure and redox properties of single-atom bridged diuranium complexes supported by aryloxides

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Luciano Barluzzi, Fang-Che Hsueh

Single-atom (group 15 and group 16 anions) bridged dimetallic complexes of low oxidation state uranium provide a convenient route to implement multielectron transfer and promote magnetic communication in uranium chemistry, but remain extremely rare. Here w ...

Diffuse spin waves and classical spin liquid behavior in the kagome antiferromagnet chromium jarosite, KCr3(OD)6(SO4)2

Ivica Zivkovic, Sofie Janas

The dynamics of the S = 3/2 kagome antiferromagnet chromium jarosite, KCr3(OD)(6)(SO4)(2), was studied using high-resolution neutron time-of-flight spectroscopy on a polycrystalline sample with a nearly stoichiometric magnetic lattice [2.8(2)% Cr vacancies ...

Electrical and Magnetic Properties of FeGa3 with Antisite Disorder

Henrik Moodysson Rønnow, Ivica Zivkovic, Ellen Fogh

We investigated the electronic and magnetic ground states of the cage compound FeGa3 under the presence of Fe antisite disorder (namely as Fe0.258Ga0.742) by x-ray diffraction (XRD), Mössbauer spectroscopy (MS), magnetization and electrical resistivity. Ou ...

Pressure dependence of superconducting properties of layered BaNi2P2

Henrik Moodysson Rønnow, Ivica Zivkovic, Richard Gaal, Youngro Lee

The discovery of unconventional superconductivity in a broad class of iron-based materials invoked extensive research on the corresponding compounds of other transition metals. For instance, BaNi2P2 exhibits a superconducting transition with a critical tem ...
