Radical TADF: Quartet‐Derived Luminescence with Dark TEMPO
Advanced Materials, EarlyView.A new class of luminescent organic quantum materials is introduced, formed by attaching a stable radical to TADF chromophores. Due to ferromagnetic exchange coupling, a high‐spin quartet state forms upon excitation, which can thermally access a bright state.

Phases and phase transitions in spin-triplet ferromagnetic superconductors
, 2004 Recent results for the coexistence of ferromagnetism and unconventional superconductivity with spin-triplet Cooper pairing are reviewed on the basis of the quasi-phenomenological Ginzburg-Landau theory. New results are reported. The results are discussed

Controlled Formation of Skyrmion Bags
Advanced Materials, EarlyView.This work demonstrates stabilization of complex magnetic skyrmion bags in ferromagnetic thin films through precisely engineered anisotropy defects using ion irradiation. The researchers achieve controlled field‐ and laser‐induced generation of skyrmionia, target skyrmions, and higher‐order skyrmion bags at room temperature. This reliable platform opens

On the theory of ferromagnetism
Physica, 1962 An attempt is made to specify the conditions under which Heisenberg's model of ferromagnetism is correct. It is found that in addition to the exchange term there are other terms in the hamiltonian, describing the effects of the band width and of polar states.

Proposing Altermagnetic‐Ferroelectric Type‐III Multiferroics with Robust Magnetoelectric Coupling
Advanced Materials, EarlyView.Multiferroics are highly sought after for advanced technological applications. Here, a novel class of type‐III multiferroics is proposed, where ferroelectricity and altermagnetism are inherently interlocked by crystal symmetry, setting them apart from conventional multiferroics. The ferroelectric switching is shown to fully invert the spin polarization

Strongly correlated electrons on frustrated lattices
Iranian Journal of Physics Research, 2008 We give an overview of recent work on charge degrees of freedom of strongly correlated electrons on geometrically frustrated lattices. Special attention is paid to the checkerboard lattice, i.e., the two-dimensional version of a pyrochlore lattice and to

Mechanophysical Synthesis of Core/Shell Hybrid Supraparticles
Advanced Materials, EarlyView.Collision‐driven mechanophysical synthesis enables rapid, chemical‐free assembly of core/shell hybrid supraparticles (HSPs) by embedding inorganic nanomaterials onto polymer microparticles. Governed by collision and interfacial energies, this scalable, solvent‐free method accommodates diverse material combinations, allowing multifunctional HSPs for ...
