Quantum criticality describes the collective fluctuations of matter undergoing a second-order
phase transition at zero temperature. Heavy-fermion metals have in recent years emerged …

We report on detailed magnetic measurements on the cubic helimagnet FeGe in external
magnetic fields and temperatures near the onset of long-range magnetic order at TC= 278.2 …

Mechanical control of magnetism is an important and promising approach in spintronics. To
date, strain control has mostly been demonstrated in ferromagnetic structures by exploiting a …

We report simultaneous measurements of the magnetization and the ac susceptibility across
the magnetic phase diagram of single-crystal MnSi. In our study we explore the importance …

The chiral helimagnet Cr 1/3 NbS 2 has been investigated by magnetic, transport, and
thermal properties measurements on single crystals and by first-principles electronic …

We review many-body effects, their microscopic origin, as well as their impact on
thermoelectricity in correlated narrow-gap semiconductors. Members of this class—such as …

We report comprehensive small angle neutron scattering measurements complemented by
ac susceptibility data of the helical order, conical phase, and Skyrmion lattice phase (SLP) in …

We study systems of bosons whose low-energy excitations are located along a spherical
submanifold of momentum space. We argue for the existence of gapless phases which we …

Abstract Domain walls naturally arise whenever a symmetry is spontaneously broken. They
interconnect regions with different realizations of the broken symmetry, promoting structure …

Helimagnets realize an effective lamellar ordering that supports disclination and dislocation
defects. Here, we investigate the micromagnetic structure of screw dislocation lines in cubic …
