High-temperature antiferromagnetism in molecular semiconductor thin films and nanostructures

Nature Communications, 2014
The viability of dilute magnetic semiconductors in applications is linked to the strength of the magnetic couplings, and room temperature operation is still elusive in standard inorganic systems.

A Review on MXene Terminations

Advanced Functional Materials, EarlyView.
Surface terminations play a decisive role in determining the properties of MXenes. Their coordination, composition and stoichiometry can be tuned both during synthesis and through post synthesis methods to tailor MXenes for optimum performance in applications. This review explores the present understanding of surface terminations.

Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe

Advanced Functional Materials, EarlyView.
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...

Spin-transfer torque induced spin waves in antiferromagnetic insulators

New Journal of Physics, 2015
We explore the possibility of exciting spin waves in insulating antiferromagnetic films by injecting spin current at the surface. We analyze both magnetically compensated and uncompensated interfaces.

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass

Advanced Functional Materials, EarlyView.
A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Prerequisite for superconductivity: appropriate spin-charge correlations

, 2008
This work investigates the relation between superconductivity and correlations. A simple calculation shows that the appropriate spin-charge correlation is the key role to any superconductivity, and this calculation is consistent with the analyses of ...
