Title: Superconducting Dome in Nd_1-xSr_xNiO₂ Infinite Layer Films

Abstract

We show the phase diagram of Nd_1-xSr_xNiO₂ infinite layer thin films grown on SrTiO₃. A superconducting dome spanning 0.125 < x < 0.25 is found, remarkably similar to cuprates, albeit over a narrower doping window. However, while cuprate superconductivity is bounded by an insulator for underdoping and a metal for overdoping, here we observe weakly insulating behavior on either side of the dome. Furthermore, the normal state Hall coefficient is always small and proximate to a continuous zero crossing in doping and in temperature, in contrast to the ~ 1/x dependence observed for cuprates. This suggests the presence of both electronlike and holelike bands, consistent with band structure calculations.

Isotropic Pauli-limited superconductivity in the infinite-layer nickelate Nd_0.775Sr_0.225NiO₂

Journal Article Wang, Bai Yang ; Li, Danfeng ; Goodge, Berit H. ; ... - Nature Physics

The recent observation of superconductivity in thin-film infinite-layer nickelates offers a different angle from which to investigate superconductivity in layered oxides. A wide range of candidate models have been proposed, which emphasize single- or multi-orbital electronic structure, Kondo or Hund’s coupling and analogies to cuprates. Further experimental characterization of the superconducting state is needed to develop a full understanding of the nickelates. Here we use magnetotransport measurements to probe the superconducting anisotropy in Nd_0.775Sr_0.225NiO₂. Here, we find that the upper critical field is surprisingly isotropic at low temperatures despite the layered crystal structure. In a magnetic field, the superconductivity ismore »« less

Aspects of the synthesis of thin film superconducting infinite-layer nickelates

Journal Article Lee, Kyuho ; Goodge, Berit H. ; Li, Danfeng ; ... - APL Materials

The recent observation of superconductivity in Nd_0.8Sr_0.2NiO₂ calls for further investigation and optimization of the synthesis of this infinite-layer nickelate structure. Here, we present our current understanding of important aspects of the growth of the parent perovskite compound via pulsed laser deposition on SrTiO₃ (001) substrates and the subsequent topotactic reduction. We find that to achieve single-crystalline, single-phase superconducting Nd_0.8Sr_0.2NiO₂, it is essential that the precursor perovskite Nd_0.8Sr_0.2NiO₃ thin film is stabilized with no visible impurity phases; in particular, a Ruddlesden–Popper-type secondary phase is often observed. We have further investigated the evolution of the soft-chemistry topotactic reduction conditions to realizemore »« less

We report the synthesis of millimeter-sized freestanding single-crystal YBa₂Cu₃O_7–x heterostructure membranes with nanoscale thickness. On a SrTiO₃ substrate, a heteroepitaxial water-soluble sacrificial layer of Sr₃Al₂O₆ followed by an encapsulated YBa₂Cu₃O_7–x film is grown by pulsed laser deposition. A freestanding YBa₂Cu₃O_7–x heterostructure membrane is obtained by etching the sacrificial layer. As a result, its high crystalline quality is demonstrated via x-ray diffraction, electrical measurements, and scanning transmission electron microscopy.

Doping dependence of the thermopower of high-[ital T][sub [ital c]] cuprates: Tight-binding band model

Journal Article Kubo, Y - Physical Review, B: Condensed Matter; (United States)

Tight-binding calculatoins are performed which include both Cu-O and O-O interactions in the CuO[sub 2] plane. These calculations reconcile inconsistencies in observed behaviors of the thermopower [ital S] and the Hall coefficient [ital R][sub [ital H]]: the sign of [ital S] of high-[ital T][sub [ital c]] cuprates at room temperature becomes negative in the overdoped regime, while [ital R][sub [ital H]] remains positive. A striking feature of the CuO[sub 2] antibonding band is that a holelike Fermi surface is formed even when the band is less than half-filled. This brings about an unusual electron state in which the Hall (cyclotron)more »« less

Ferromagnetic order beyond the superconducting dome in a cuprate superconductor

Journal Article Sarkar, Tarapada ; Wei, D. S. ; Zhang, J. ; ... - Science

According to conventional wisdom, the extraordinary properties of the cuprate high-temperature superconductors arise from doping a strongly correlated antiferromagnetic insulator. The highly overdoped cuprates—whose doping lies beyond the dome of superconductivity—are considered to be conventional Fermi liquid metals. We report the emergence of itinerant ferromagnetic order below 4 kelvin for doping beyond the superconducting dome in thin films of electron-doped La _2– _x Ce _x CuO ₄ (LCCO). The existence of this ferromagnetic order is evidenced by negative, anisotropic, and hysteretic magnetoresistance, hysteretic magnetization, and the polar Kerr effect, all of which are standard signatures of itinerant ferromagnetism in metals.more »« less
