A pane of window glass and a piece of quartz are both are transparent to light, but their atomic structure is very different. Quartz is crystalline at the atomic level while window glass is amorphous. This can also occur with magnetism at the atomic level in solids containing magnetic states such as antiferromagnetism (ordered) and spin-glass (disorded). This work describes the interaction (exchange bias) between ordered and disordered magnetic states and how the magnetic properties of the material are altered as a result.
This work reports the first observation of the dynamical generation of a spin polarized current from an antiferromagnetic material into an adjacent non-magnetic material and its subsequent conversion into electrical signals
A new experimental technique allowed physicists to precisely probe the electron spins of an intriguing compound and uncover unexpected behavior.
This research clarifies fundamental relationships between magnetism, superconductivity and the nature of the enigmatic “pseudogap state" in cuprate superconductors. The discovery provides an additional puzzle piece in the theoretical understanding of high-temperature superconductors - a key towards improving and utilizing these materials for technological applications.
Using intense pulsed magnetic fields and measurements at low temperatures, MagLab users have found evidence of a long-sought “spin liquid” in terbium indium oxide (TbInO3)
The findings contribute to scientists' understanding of magnetic materials that could point the way to future applications.
Scientists used high magnetic fields and low temperatures to study crystals of URu2–xFexSi2. Using these conditions, they explored an intriguing state of matter called the "hidden order phase" that exhibits emergent behavior. Emergent behavior occurs when the whole is greater than the sum of its parts, meaning the whole has exciting properties that its parts do not possess; it is an important concept in philosophy, the brain and theories of life. This data provide strict constraints on theories of emergent behavior.
New materials that exhibit a strong coupling between magnetic and electric effects are of great interest for the development of high-sensitivity detectors and other devices. This paper reports on such a coupling in a specially designed material.
Researchers discover that Sr1-yMn1-zSb2 (y,z < 0.1) is a so-called Weyl material that holds great promise for building devices that require far less power.
