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

open access: yes, 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 ...

Antiferromagnetic Spin Seebeck Effect [PDF]

open access: yesPhysical Review Letters, 2016
We report on the observation of the spin Seebeck effect in antiferromagnetic MnF$_2$. A device scale on-chip heater is deposited on a bilayer of Pt (4 nm)/MnF$_2$ (110) (30 nm) grown by molecular beam epitaxy on a MgF$_2$ (110) substrate. Using Pt as a spin detector layer it is possible to measure thermally generated spin current from MnF$_2$ through ...

Coexistence of Spin Canting and Metamagnetism in a One-Dimensional Mn(II) Compound Bridged by Alternating Double End-to-End and Double End-On Azido Ligands and the Analog Co(II) Compound

open access: yesMagnetochemistry, 2021
Two new compounds of general formula [M(N3)2(dmbpy)] in which dmbpy = 5,5′-dimethyl-2,2′-bipyridine, and M = Mn(II) or Co(II), have been solvothermally synthesized and characterized structurally and magnetically.

Interplay between Superconductivity and Antiferromagnetism in a Multi-layered System

open access: yes, 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.

Spin Glass and antiferromagnetism in Kondo lattice disordered systems [PDF]

open access: yes, 2003
The competition between spin glass (SG), antiferromagnetism (AF) and Kondo effect is studied here in a model which consists of two Kondo sublattices with a gaussian random interaction between spins in differents sublattices with an antiferromagnetic mean

High-pressure synthesis and magnetic properties of tetragonal R2BaCuO5 (R = Sm and Eu)

open access: yesFrontiers in Chemistry, 2023
We report the experimental discovery of a new structural phase of well-known orthorhombic R2BaCuO5 (R = Sm and Eu), exhibiting a tetragonal crystal structure with space group P4∕mbm.

Phononic manipulation of antiferromagnetic domains in NiO

open access: yesNew Journal of Physics, 2022
The interaction between the crystal lattice and spins appears to be a very efficient mechanism for non-thermal manipulation of magnetic order. A particularly intriguing question is whether lattice vibrations can also be used to control or even switch ...

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

open access: yes, 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.

Classical Antiferromagnetism in Kinetically Frustrated Electronic Models [PDF]

open access: yes, 2014
We study the infinite U Hubbard model with one hole doped away half-filling, in triangular and square lattices with frustrated hoppings that invalidate Nagaoka's theorem, by means of the density matrix renormalization group.
