We consider the nanoscale electronic phase separation in a wide class of different
materials, mostly in strongly correlated electron systems. The phase separation turns out to …

It has recently been established that the high-transition-temperature (high-T c)
superconducting state coexists with short-range charge-density-wave order,,,,,,,,,, and …

Cobaltates with 3 d based layered honeycomb structure were recently proposed as Kitaev
magnets and putative candidates to host the long-sought Kitaev spin liquid. Here we present …

Nanoscale phase separation (NPS), characterized by particular types of correlated
disorders, plays an important role in the functionality of high-temperature superconductors …

Magnetoelectric multiferroics have attracted enormous attention in the past years because of
their high potential for applications in electronic devices, which arises from the intrinsic …

Complex low-temperature-ordered states in chiral magnets are typically governed by a
competition between multiple magnetic interactions. The chiral-lattice multiferroic …

In this paper, a uniform and defective LaSrCoO 4 was prepared by using amino acid derived
surfactant (N-(2-hydroxylalkyl)-l-Phenylalanine). Owing to rich active groups of N-(2 …

The magnetic excitation spectrum of most high-temperature superconducting (HTSC)
cuprates is hour-glass shaped. The observation of hour-glass spectra in the isostructural Sr …

We derived simple rules for the sign of 180∘ superexchange interaction based on the
multielectron calculations of the superexchange interaction in the transition metal oxides that …

La2CoO4+ δ is a strongly correlated oxide with exciting physical and electronic properties
originating from the subtle interplay of the lattice, orbital, charge, and spin degrees of …
