Large Enhancement of Ferromagnetism under a Collective Strong Coupling of YBCO Nanoparticles [PDF]
Nano letters (Print), 2021 Light–Matter strong coupling in the vacuum limit has been shown, over the past decade, to enhance material properties. Oxide nanoparticles are known to exhibit weak ferromagnetism due to vacancies in the lattice.

Emergent ferromagnetism near three-quarters filling in twisted bilayer graphene [PDF]
Science, 2019 Twisted bilayer graphene goes magnetic When two layers of graphene in a bilayer are twisted with respect to each other by just the right, “magic,” angle, the electrons in the system become strongly correlated. As the electronic density is tuned by gating,

On the Absence of Ferromagnetism in Typical 2D Ferromagnets [PDF]
Communications in Mathematical Physics, 2007 We consider the Ising systems in $d$ dimensions with nearest-neighbor ferromagnetic interactions and long-range repulsive (antiferromagnetic) interactions which decay with a power, $s$, of the distance. The physical context of such models is discussed; primarily this is $d=2$ and $s=3$ where, at long distances, genuine magnetic interactions between ...

Imaging orbital ferromagnetism in a moiré Chern insulator [PDF]
Science, 2020 Capturing exotic magnetism Ferromagnetism is associated with the breaking of time-reversal symmetry, most frequently by the spin degree of freedom. Although the orbital motion of electrons can also contribute to ferromagnetism, in most materials, it is ...

Scientific Reports, 2014 AbstractThe non-magnetic and non-Fermi-liquid CaRuO3 is the iso-structural analog of the ferromagnetic (FM) and Fermi-liquid SrRuO3. We show that an FM order in the orthorhombic CaRuO3 can be established by the means of tensile epitaxial strain. The structural and magnetic property correlations in the CaRuO3 films formed on SrTiO3 (100) substrate ...

Emergent ferromagnetism with superconductivity in Fe(Te,Se) van der Waals Josephson junctions
Nature Communications, 2023 Ferromagnetism and superconductivity are two key ingredients for topological superconductors, which can serve as building blocks of fault-tolerant quantum computers. Adversely, ferromagnetism and superconductivity are typically also two hostile orderings

Ferromagnetism in 2D Vanadium Diselenide. [PDF]
ACS Nano, 2021 Two-dimensional (2D) van der Waals ferromagnets carry the promise of ultimately miniature spintronics and information storage devices. Among the 2D ferromagnets, all inherit the magnetic ordering from their bulk ancestors.

Terahertz Spin Current Pulses in Antiferromagnetic Oxide: The Role of Vacancy‐Induced Ferromagnetism
Small Structures, 2023 Antiferromagnetic oxides have attracted increasing attention for their outstanding peculiarities in spintronics. Crystal lattice defects that are present in antiferromagnetic oxides can influence their physical properties, such as vacancy‐induced ...
