Universal Superconductivity in FeTe and All‐Iron‐Based Ferromagnetic Superconductor Heterostructures

Advanced Functional Materials, EarlyView.
The first all‐iron‐based ferromagnetic superconductor heterostructures with high‐temperature superconductivity and strong ferromagnetism aredemonstrated. From this, it is discovered that FeTe becomes universallysuperconducting with a minute level of cationic impurities through doping ordiffusion from neighboring layers, suggesting its ground state can ...

Evidence of Long‐Range Dzyaloshinskii–Moriya Interaction at Ferrimagnetic Insulator/Nonmagnetic Metal Interfaces

Advanced Functional Materials, EarlyView.
This study demonstrates that in sputter‐deposited Tb3Fe5O12 (TbIG)/nonmagnetic metal (NM) heterostructures, the interfacial Dzyaloshinskii–Moriya Interaction (DMI) originates at the TbIG/NM interface. Furthermore, measurements suggest a significant interfacial DMI arising from a second non‐local interface, created by inserting a Cu spacer layer between

Coexistence of Antiferromagnetism and Triplet Superconductivity

, 2004
The authors discuss the possibility of coexistence of antiferromagnetism and triplet superconductivity as a particular example of a broad class of systems where the interplay of magnetism and superconductivity is important. This paper focuses on the case

Quantum Antiferromagnetism in Quasicrystals [PDF]

Physical Review Letters, 2003
The antiferromagnetic Heisenberg model is studied on a two-dimensional bipartite quasiperiodic lattice. The distribution of local staggered magnetic moments is determined on finite square approximants with up to 1393 sites, using the Stochastic Series Expansion Quantum Monte Carlo method. A non-trivial inhomogeneous ground state is found.

ErMn6Sn6: A Promising Kagome Antiferromagnetic Candidate for Room‐Temperature Nernst Effect‐Based Thermoelectrics

Advanced Functional Materials, EarlyView.
This work investigates the Nernst effect in the Kagome magnet ErMn6Sn6 which exhibits both topological and anomalous Nernst effects with the anomalous Nernst coefficient reaching 1.71 µV K⁻¹ at 300 K. This value surpasses that of most canted antiferromagnetic materials, making ErMn6Sn6 a promising candidate for advancing thermoelectric devices based on

Quantum corrections to the phase diagram of heavy-fermion superconductors

, 2005
The competition between magnetism and Kondo effect is the main effect determining the phase diagram of heavy fermion systems. It gives rise to a quantum critical point which governs the low temperature properties of these materials. However, experimental

Effects of Chemical Pressure on Superconductivity in Electrochemically Intercalated (TMA)yFe2(Se1−xSx)2 (TMA = Tetramethylammonium)

Advanced Functional Materials, EarlyView.
Intercalation of a series of FeSe1−xSx host crystals with tetramethylammonium cations (TMA+) linearly scales the critical temperature Tc from 43 K down to 28 K with increasing sulfur incorporation. The chemical pressure induced by the partial substitution shows a weakening of the superconducting properties in both hosts and intercalates in a remarkably

Two-Fermi-surface superconducting state and a nodal d-wave gap in the electron-doped Sm(1.85)Ce(0.15)CuO(4-d) cuprate superconductor

, 2011
We report on laser-excited angle-resolved photoemission spectroscopy (ARPES) in the electron-doped cuprate Sm(1.85)Ce(0.15)CuO(4-d). The data show the existence of a nodal hole-pocket Fermi-surface both in the normal and superconducting states.
