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 ...

Anomalous Ferromagnetic Phase in the Gd_1−xEr_xB₄ Series: Crystal Growth, Thermal, and Magnetic Properties

Crystals, 2023
Rare-earth tetraborides RB4 are of great interest due to the occurrence of geometric magnetic frustration and corresponding unusual magnetic properties. While the Gd3+ spins in GdB4 align along the ab plane, Er3+ spins in the isomorphic ErB4 are confined

Interplay between different states in heavy fermion physics

, 2006
Calorimetry experiments under high pressure were used to clarify the interplay between different states such as superconductivity and antiferromagnetism in CeRhIn5, spin density wave and large moment antiferromagnetism in URu2Si2.

Effect of Co-Doping on the Magnetic Ground State of the Heavy-Fermion System CeCu₂Ge₂ Studied by Neutron Diffraction

Magnetochemistry, 2023
The antiferromagnetic phase transition of the heavy-fermion system Ce(Cu1−xCox)2Ge2 for x = 0.05 and 0.2, showing up in specific heat, magnetic susceptibility, and muon spin relaxation (μSR) data, has been further investigated.

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

Concepts of antiferromagnetic spintronics [PDF]

physica status solidi (RRL) – Rapid Research Letters, 2017
Antiferromagnetic spintronics is an emerging research field whose focus is on the electrical, optical or other means of control of the antiferromagnetic order parameter and its utility in information technology devices. An example of recently discovered new concepts is the Néel spin–orbit torque which allows for the antiferromagnetic order parameter to

Effect of hydrostatic pressure on the ambient pressure superconductor CePt_3Si

, 2004
We studied the evolution of superconductivity (sc) and antiferromagnetism (afm) in the heavy fermion compound CePt_3Si with hydrostatic pressure. We present a pressure-temperature phase diagram established by electrical transport measurements.
