Abstract Two different ferroelectric materials, Sr0.95Ba0.05TiO3 and Sr0.985Ca0.015TiO3, can be turned into polar metals with broken centrosymmetry via electron doping. Systematic substitution of Nb5+ for Ti4+ has revealed that these polar metals bot

Among its interesting properties, SrTiO3 can show both superconductivity and ferroelectric quantum criticality at low temperatures. Tomioka et al. use La and oxygen-isotope doping to tune electron-doped SrTiO3 to the critical region and observe enhan

We show that ground state phase competition significantly decreases the critical cooling rate required for the kinetic avoidance of a first-order phase transition and thus facilitates the creation of metastable electronic states. This principle is re

Using THz spectroscopy, we show that the spin-wave spectrum of multiferroic BiFeO$_3$ in its high-field canted antiferromagnetic state is well described by a spin model that violates rhombohedral symmetry. We demonstrate that the monoclinic distortio

We observe thermal Hall conductivity for ${({\mathrm{Tb}}_{0.3}{\mathrm{Y}}_{0.7})}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}_{7}$, which is even larger than the previously observed thermal Hall conductivity for ${\mathrm{Tb}}_{2}{\mathrm{Ti}}_{2}{\mathrm{O}}

Using the laser diode floating zone method, single crystals of LaNiO3, a nickel oxide with perovskite structure, have been successfully prepared under a high oxygen pressure of 4 MPa (40 bar). Sing...

The reduction of Si concentration in β-Ga2O3 crystals by the zone refining method was investigated. By the chemical analysis of a quenched β-Ga2O3 crystal coexisting with its melt at high temperature, the segregation coefficient for Si was estimate
