In chemistry and biochemistry, chirality represents the structural asymmetry characterized by
nonsuperimposable mirror images for a material such as DNA. In physics, however, chirality …

The interplay between chirality and topology nurtures many exotic electronic properties. For
instance, topological chiral semimetals display multifold chiral fermions that manifest …

Abstract Spin-Orbit Torque (SOT) Magnetic Random-Access Memory (MRAM) devices offer
improved power efficiency, nonvolatility, and performance compared to static RAM, making …

The position operator in a Bloch representation acquires a gauge correction in the
momentum space on top of the canonical position, which is called the anomalous position …

Spintronics has been extensively explored over the past decades, focusing primarily on the
spin characteristic of the electron, while the orbital feature of the electron has been …

The orbital Hall effect generates a current of orbital angular momentum perpendicular to a
charge current. Experiments suggest that this orbital current decays on a long length scale …

Recently, orbital Hall current has attracted attention as an alternative method to switch the
magnetization of ferromagnets. Here we present our findings on electrical switching of the …

We performed spin-torque ferromagnetic resonance studies on the Al/NiFe/AlO x
heterostructure. We observed a large non-trivial field-like torque, τ FL z⁠, due to the out-of …

The interplay between spin currents and orbital momentum currents is fundamental in the
emerging field of orbitronics, particularly when considering nanoscale features. Unlike spin …

Experimental demonstration of substantially large and negative spin Hall angle in CuBi
alloys, in which diluted Bi atoms are doped into Cu, sheds light on a novel aspect of spin …
