Chemical and physical pressure effects in the A-site spinel antiferromagnets CoM2O4 (M = Al, Co, and Rh)

Materials Research Express, 2020
Magnetic phase transitions under high pressure are reported for the diamond lattice antiferromagnet Co _3−x Rh _x O _4 in the range of 0 ≤  x  ≤ 2.0, which is an isostructural S  = 3/2 system for the well-known frustrated antiferromagnet CoAl _2 O _4 ...

Coexistence of Antiferromagnetism and Superconductivity in Electron-doped High-Tc Superconductors

, 2007
We present magnetotransport evidence for antiferromagnetism in films of the electron-doped cuprates Pr$_{2-x}$Ce$_x$CuO$_4$. Our results show clear signature of static antiferromagnetism up to optimal doping x=0.15, with a quantum phase transition close ...

Hybrid-Density Functional Calculations of Structural, Electronic, Magnetic, and Thermodynamic Properties of α-Cu₂P₂O₇

Applied Sciences, 2022
We present a comparative study (using PBE, PBE0, and HSE functionals) of electronic and atomic structure, magnetism, and phonon dispersion relations of α-Cu2P2O7. Four possible magnetic configurations are considered, FM, AFM-1, AFM-2, and AFM-3.

Interplay between Superconductivity and Antiferromagnetism in a Multi-layered System

, 2011
Based on a microscopic model, we study the interplay between superconductivity and antiferromagnetism in a multi-layered system, where two superconductors are separated by an antiferromagnetic region.

Doping-Enhanced Antiferromagnetism in Ca1-xLaxFeAs2 [PDF]

, 2015
In iron pnictides, high temperature superconductivity emerges after suppressing antiferromagnetism by doping. Here we show that antiferromagnetism in Ca$_{1-x}$La$_x$FeAs$_2$ is robust against and even enhanced by doping. Using $^{75}$As-nuclear magnetic

Renormalized mean-field analysis of antiferromagnetism and d-wave superconductivity in the two-dimensional Hubbard model

, 2006
We analyze the competition between antiferromagnetism and superconductivity in the two-dimensional Hubbard model by combining a functional renormalization group flow with a mean-field theory for spontaneous symmetry breaking.

A New Fe^III Substituted Arsenotungstate [Fe^III₂(As^IIIW₆O₂₃)₂(As^IIIO₃H)₂]¹²⁻: Synthesis, Structure, Characterization and Magnetic Properties

Magnetochemistry, 2020
The iron(III)-containing arsenotungstate [FeIII2(AsIIIW6O23)2(AsIIIO3H)2]12− (1) was prepared via a simple, one-pot reaction in aqueous basic medium. The compound was isolated as its sodium salt, and structurally-characterized by Single Crystal X-ray ...
