Title: Mini volume collapse as evidence for a three-body magnetic polaron in $S m_{1 - x} E u_{x} S$

Abstract

Samarium sulfide (SmS) is a nonmagnetic narrow-gap (0.06 eV) semiconductor that undergoes a transition to a metallic intermediate valence state at 6.5 kbar. Europium sulfide (EuS) is a ferromagnetic semiconductor with a Curie temperature of 16 K and a gap of 1.6 eV. Here we present a study of the lattice constant, magnetic susceptibility, and resistivity of the substitution series Sm_1-x Eu_x S for 0 < x < 1. We observe a smooth interpolation of magnetic and transport behavior across the series, consistent with a virtual crystal scenario and Vegard’s law. Surprisingly, however, the lattice constant deviates below Vegard’s law in a manner that suggests parametric control of the Sm-Sm distance by the Eu moment in the manner of a magnetic polaron.

Lack of superconductivity in the phase diagram of single-crystalline $Eu {(F e_{1 - x} C o_{x})}_{2} A s_{2}$ grown by transition metal arsenide flux

Journal Article Wang, Gang ; Meier, William R. ; Straszheim, Warren E. ; ... - Physical Review Materials

Here, the interplay of magnetism and superconductivity (SC) has been a focus of interest in condensed matter physics for decades. EuFe₂As₂ has been identified as a potential platform to investigate interactions between structural, magnetic, and electronic effects as well as the coexistence of magnetism and SC with similar transition temperatures. However, there are obvious inconsistencies in the reported phase diagrams of Eu(Fe_1–xCo_x)₂As₂ crystals grown by different methods. For transition metal arsenide (TMA)-flux-grown crystals, even the existence of SC is uncertain. Here we reexamine the phase diagram of single-crystalline Eu(Fe_1–xCo_x)₂As₂ grown by TMA flux. We found that the lattice parameter cmore »« less

Out-of-plane magnetic anisotropy enhancement in $L a_{1 - x} S r_{x} Co O_{3 - δ} / L a_{2 / 3} S r_{1 / 3} Mn O_{3} / L a_{1 - x} S r_{x} Co O_{3 - δ}$ thin films

Journal Article Wang, Wei ; Zhang, Jine ; Shen, Xi ; ... - Physical Review B

Perpendicular magnetic anisotropy (PMA) in multilayer thin films promotes the development of spintronic and magnonic research fields. The origin of the PMA deserves a thorough investigation since it contains rich physics related to multiple factors in the heterostructure system. In this report, we study the origin of PMA in La_2/3Sr_1/3 Mn O₃ (LSMO) thin films sandwiched by La_1-xSr_xCoO_3-δ (LSCO) layers grown on SrTiO₃ substrate, using aberration-corrected scanning transmission electron microscopy. Our findings indicate that the lattice and electronic structures of LSMO can be modified through the inhomogeneous strains induced by nanodomains in LSCO layers. Moreover, we infer that the latticemore »« less

We investigate doping- and pressure-induced changes in the electronic state of Mn 3d and As 4p orbitals in II-II-V based diluted magnetic semiconductor (Ba_1-x,K_x)(Zn_1-y,Mn_y)₂As₂ to shed light into the mechanism of indirect exchange interactions leading to high ferromagnetic ordering temperature (T_c = 230 K in optimally doped samples). A suite of x-ray spectroscopy experiments (emission, absorption and dichroism) show that the emergence, and further enhancement of ferromagnetic interactions with increased hole doping into the As 4p band is accompanied by a decrease in local 3d spin density at Mn sites. This is a result of increasing Mn 3d - Asmore »« less

Ion-gel-gating-induced oxygen vacancy formation in epitaxial $L a_{0.5} S r_{0.5} Co O_{3 - δ}$ films from in operando x-ray and neutron scattering

Journal Article Walter, Jeff ; Yu, Guichuan ; Yu, Biqiong ; ... - Physical Review Materials

Ionic-liquid/gel-based transistors have emerged as a potentially ideal means to accumulate high charge-carrier densities at the surfaces of materials such as oxides, enabling control over electronic phase transitions. Substantial gaps remain in the understanding of gating mechanisms, however, particularly with respect to charge carrier vs oxygen defect creation, one contributing factor being the dearth of experimental probes beyond electronic transport. Here we demonstrate the use of synchrotron hard x-ray diffraction and polarized neutron reflectometry as in operando probes of ion-gel transistors based on ferromagnetic La_0.5Sr_0.5CoO_3-δ. An asymmetric gate-bias response is confirmed to derive from electrostatic hole accumulation at negative gatemore »« less

Closure of the Mott gap and formation of a superthermal metal in the Fröhlich-type nonequilibrium polaron Bose-Einstein condensate in $U O_{2 + x}$

Journal Article Conradson, Steven D. ; Andersson, David A. ; Boland, Kevin S. ; ... - Physical Review B

Mixed valence O-doped UO_2+x and photoexcited UO₂ containing transitory U³⁺ and U⁵⁺ host a coherent polaronic quantum phase (CPQP) that exhibits the characteristics of a Fröhlich-type, nonequilibrium, phonon-coupled Bose-Einstein condensate whose stability and coherence are amplified by collective, anharmonic motions of atoms and charges. Complementary to the available, detailed, real space information from scattering and EXAFS, an outstanding question is the electronic structure. Mapping the Mott gap in UO₂, U₄O₉, and U₃O₇ with O XAS and NIXS and UM5 RIXS shows that O doping raises the peak of the U5f states of the valence band by ~0.4 eV relative tomore »« less
