ABSTRACT: Narrow-gap semiconductors are sought-after materials due to their potential for long-wavelength detectors, thermoelectrics, and more recently non-trivial topology. Here we report the synthesis and characterization of a new family of narrow-

Quantum Criticality in a Layered Iridate

Autor: Samanta, Kousik, Souza, Jean C., Rigitano, Danilo, Morales, Adimir I., Pagliuso, Pascoal G., Granado, Eduardo

Publikováno v: Communications Physics 4, 89 (2021)

Iridates provide a fertile ground to investigate correlated electrons in the presence of strong spin-orbit coupling. Bringing these systems to the proximity of a metal-insulator quantum phase transition is a challenge that must be met to access quant

Anisotropic magnetic excitations and incipient N\'eel order in Ba(Fe$_{1-x}$Mn$_{x}$)$_{2}$As$_{2}$

Autor: Garcia, Fernando A., Ivashko, Oleh, McNally, Daniel E., Das, Lakshmi, Piva, Mario M., Adriano, Cris, Pagliuso, Pascoal G., Chang, Johan, Schmitt, Thorsten, Monney, Claude

Publikováno v: Phys. Rev. B 99, 115118 (2019)

It is currently understood that high temperature superconductivity (SC) in the transition metal $(M)$ substituted iron arsenides Ba(Fe$_{1-x}$$M$$_{x}$)$_{2}$As$_{2}$ is promoted by magnetic excitations with wave vectors $(\pi,0)$ or $(0,\pi)$. It is

Critical Field Determination in Organic Antiferromagnet F4BImNN

Autor: Adriano, Cris, Freitas, Rafael S., Paduan-Filho, Armando, Pagliuso, Pascoal G., Oliveira Jr., Nei Fernandes, Lahti, Paul M.

A combination of magnetic heat capacity measurements versus temperature under multiple fixed external fields using a polycrystalline sample, plus easy and hard axis aligned magnetization versus field measurements using a single crystal of the radical

Incoherent electronic band states in Mn substituted BaFe$_{2}$As$_{2}$

Autor: Cantarino, Marli R., Pakuszewski, Kevin R., Salzmann, Björn, Moya, Pedro H. A., Neto, Wagner R. da Silva, Freitas, Gabriel S., Pagliuso, Pascoal G., Monney, Claude, Adriano, Cris, Garcia, Fernando A.

Chemical substitution is commonly used to explore new ground states in materials, yet the role of disorder is often overlooked. In Mn-substituted BaFe$_{2}$As$_{2}$ (MnBFA), superconductivity (SC) is absent, despite being observed for nominal hole-do
