Exploration of new ferroic (ferroelectric, ferromagnetic or ferroelastic) materials continues to be a central theme in condensed matter physics and to drive advances in key areas of technology. Here, using thin-film composition spreads, we have mapped the functional phase diagram of the Ni-Mn-Ga system whose Heusler composition Ni(2)MnGa is a well known ferromagnetic shape-memory alloy. A chara...

Copper-oxide-based high-temperature superconductors have complex phase diagrams with multiple ordered phases. It even appears that the highest superconducting transition temperatures for certain cuprates are found in samples that display simultaneous onset of magnetism and superconductivity. We show here how the thermodynamics of fluid mixtures-a touchstone for chemistry as well as hard and sof...

Perovskite ABO3 oxides display many promising functional properties including ferroelectricity and magnetism. An ongoing challenge has been to design and synthesize materials in which ferroelectric and magnetic orderings not only coexist in a single phase above room temperature, but also are nontrivially coupled. Such a cross coupling between these different ferroic orderings could lead to many...

RV6Sn6 (R=rare earth) compounds are appealing materials platforms for exploring the interplay between R-site magnetism and nontrivial band topology associated with nonmagnetic vanadium-based kagome network. Here we present synthesis characterization of metal TbV6Sn6 via single-crystal x-ray diffraction, magnetization, transport, heat capacity measurements. Magnetization measurements reveal stro...

In a recent paper, 8 semileptonic parameters were defined to specify the most general Lorentz-invariant spin correlation functions for 2-body τ decays. These parameters can be used to search for anomalous ΓL, ΓT polarized-partial widths, for non-CKM-type leptonic CP violation, and for leptonic T̃FS violation. They can also be used to bound the effective-mass scales Λ for “new physics” arising fr...

This paper reviews some of the most recent advances in the application of the Hanle effect to solar physics, and how these developments are allowing us to explore the magnetism of the photospheric regions that look “empty” in solar magnetograms—that is, the Sun’s “hidden” magnetism. In particular, we show how a joint analysis of the Hanle effect in atomic and molecular lines indicates that ther...

Fe3N submicrorods with desirable magnetic properties were prepared from a designed metal-organic framework precursor via a modified ethanediamine nitridation route. Magnetic resonance imaging using the Fe3N submicrorods was investigated carefully, confirming the Fe3N submicrorod could be acceptable as a significant contrast agent for its outstanding concentration dependent signal and high r2 re...

The recent application of the total scattering method to magnetic systems is discussed. The ability to determine the magnetic pair distribution function opens the door to the study of local order in magnetic systems ranging from multiferroics to dilute magnetic semiconductors.
