Long after the heady days of high‐temperature superconductivity, the oxides came back into
the limelight in 2004 with the discovery of the 2D electron gas (2DEG) in SrTiO3 (STO) and …

This review provides a perspective on recent developments and their implications for our
understanding of novel quantum phenomena in the physics of two-dimensional organic …

A recent focus of quantum spin liquid (QSL) studies is how disorder/randomness in a QSL
candidate affects its true magnetic ground state. The ultimate question is whether the QSL …

The lightly doped BaFe 12− x D x O 19 (D= Al 3+, In 3+; x= 0.1 and 0.3) polycrystalline
hexaferrite samples have been investigated by powder neutron diffractometry as well as by …

The most fascinating feature of certain two-dimensional (2D) gapless quantum spin liquid
(QSL) is that their spinon excitations behave like the fermionic carriers of a paramagnetic …

Quantum spin liquids are a class of magnetic ground states reliant on non-local
entanglement. Motivated by recent advances in the control of ultracold polar molecules and …

Coexistence of ferroelectricity and ferromagnetism in one single phase of a solid is of great
interest because of the potential application for novel electronic devices. We report on the …

Double substitution of strontium hexaferrite by calcium and aluminum leads to a tremendous
rise of hard magnetic properties, such as coercivity and natural ferromagnetic resonance …

The emergence of complex and fascinating states of quantum matter in the neighborhood of
zero temperature phase transitions suggests that such quantum phenomena should be …

Mott insulators are commonly pictured with electrons localized on lattice sites, with their low-
energy degrees of freedom involving spins only. Here, we observe emergent charge …
