The magnetic shape-memory effect – magnetic-field-induced plastic deformations that return to the initial shape upon heating – is intensively studied in intermetallic Heusler materials. Here, the authors see this effect for the metallic oxide SrRuO, which exhibits a structural phase transition at high temperature and ferromagnetic ordering at six times a lower temperature. Neutron diffraction and macroscopic analyses on SrRuO single crystals show that moderate magnetic fields induce strong structural deformations resulting from the rearrangement of structural domains. The shape-memory effect is observed by modest heating to the paramagnetic phase, where the initial arrangement of structural domains already recovers, although the temperature remains well below the structural phase transition.

Electrical injection of spin current via the spin Hall effect has a huge technological implication for spin transfer torque devices and in magnon spintronics. This effect generates a spin current perpendicular to a charge current but has so far relied on expensive heavy metals. This paper uncovers a new mechanism present in ferromagnets, the anomalous spin Hall effect, where the magnetization of the ferromagnet is used to tune the spin injection efficiency up to a level greater than that found in heavy metals. The authors demonstrate this anomalous mechanism via an experimental advance where nonlocal magnon transport in a ferrimagnetic insulator (YIG) was achieved using a ferromagnetic metal (permalloy) for efficient and tunable electrical injection and detection of magnons.

The author provides a full theoretical description of current transport in finite-size superconductors with variable attractive pairing interaction. The solution shows an intricate interplay between strong quantum fluctuations induced by the finite system size and the interaction strength, which tunes a BEC-BCS crossover. The results explain a recent experiment on mesoscopic superconducting semiconductor nanowires and point the way to a systematic understanding of mesoscopic fluctuations in superconductors. In particular, the study identifies the first experimental detection of a fundamental quantity in mesoscopic superconductivity, the parity parameter.

In the one-monolayer FeSe film on SrTiO, which is a new member of high-temperature superconductor family, there exists two competing proposals on the nature of the ground state in the parent undoped film: strongly correlated insulator (as in copper-oxide superconductors) versus moderately correlated metal (as in iron-based superconductors). Here, the authors provide experimental evidence for the metallic nature by performing angle-resolved photoemission spectroscopy on an undoped one-monolayer FeSe film prepared by careful post-growth annealing. The authors demonstrate the materialization of an ideal two-dimensional Dirac electron system, where only the Dirac-cone band crosses the Fermi level, unlike in the multilayer counterpart.

The phase diagram of 1-TaS involves many different solid-state phases, including several different kinds of charge-density-wave (CDW) phase both commensurate and incommensurate with the underlying lattice. Recent experiments have shown that it is possible to drive transitions between these phases with intense femtosecond pulses of light. This work focuses on the light-driven transition from the nearly commensurate CDW phase to the incommensurate phase, using time-resolved x-ray diffraction. The authors find that the new incommensurate domains grow in a self-similar way. They also employ a double-pump method to study the dynamics and stability of the novel incommensurate phase during growth.

Until recently, many authors remained skeptical about the presence of charge order in superconducting cuprates. As early as 1999, Hunt . [Phys. Rev. Lett. 82, 4300] demonstrated that superconducting LaSrCuO (T=30 K) shares nearly identical, peculiar NMR anomalies observed at the charge order transition of Nd codoped LaNdSrCuO (suppressed T=6 K). In particular, Cu NMR signals gradually disappear in the charge ordered state. Where did the wiped out Cu NMR signals go? The authors here take full advantage of advancements in the instrumental technologies of NMR over the last two decades, and finally solve this mystery.

Conversion of conventional spin-singlet Cooper pairs into spin-triplet pairs inside a Josephson junction enables supercurrent to propagate over long distances through ferromagnetic materials. Several groups have shown how to turn the spin-triplet supercurrent on or off by varying the relative orientations of the magnetizations in multiple ferromagnetic layers inside the junction. This paper introduces a new magnetic configuration involving a synthetic antiferromagnet (SAF) with perpendicular magnetic anisotropy (PMA) that can be patterned into nanomagnets with very low stray fields. The authors suggest that this configuration will enable the controlled manipulation of the ground-state phase shift across the spin-triplet Josephson junctions to be either 0 or .

Conversion of conventional spin-singlet Cooper pairs into spin-triplet pairs inside a Josephson junction enables supercurrent to propagate over long distances through ferromagnetic materials. Several groups have shown how to turn the spin-triplet supercurrent on or off by varying the relative orientations of the magnetizations in multiple ferromagnetic layers inside the junction. This paper introduces a new magnetic configuration involving a synthetic antiferromagnet (SAF) with perpendicular magnetic anisotropy (PMA) that can be patterned into nanomagnets with very low stray fields. The authors suggest that this configuration will enable the controlled manipulation of the ground-state phase shift across the spin-triplet Josephson junctions to be either 0 or .
