Over the past decade, materials that combine broken inversion symmetry with metallic
conductivity have gone from a thought experiment to one of the fastest growing research …

The notion of a simple ordered state implies homogeneity. If the order is established by a
broken symmetry, the elementary Landau theory of phase transitions shows that only one …

We show how complex modulated order can spontaneously emerge when magnetic
interactions compete in a metal with polar lattice distortions. Combining neutron and …

Here we compare two kinds of doping in transition metal oxides by considering defects due
to the substitution of the transition metal or rare earth element. The focus is on insulating t 2 …

We report a comprehensive experimental investigation of the magnetic structure of the
cycloidal phase in Ca 3 Ru 2 O 7, which mediates the spin reorientation transition and …

Polar metals exist as a rather unique class of materials as they combine two seemingly
mutually exclusive properties (polar order and metallicity) in one system. So far only a few …

We report the magnetic and electronic properties of the bilayer ruthenate S r 3 R u 2 O 7
upon Fe substitution for Ru. We find that S r 3 (R u 1− x F ex) 2 O 7 shows a spin-glass-like …

Abstract Bilayer ruthenate Ca 3 (Ru 1− x Fe x) 2 O 7 (x= 0.05) exhibits an incommensurate
magnetic soliton lattice driven by the Dzyaloshinskii–Moriya interaction. Here we report …

We report detailed magnetic, transport, heat-capacity, and neutron-diffraction measurements
of Ba 5 Ru 3 O 12, a compound consisting of isolated Ru 3 O 12 trimers. We show that this …

The burgeoning field of quantum materials concerns systems that do not adhere to the
traditional theories of condensed matter physics. A key feature of these materials is a strong …
