Antiferromagnetic real-space configuration probed by dichroism in scattered x-ray beams with orbital angular momentum
Margaret R. McCarter, Ahmad I. U. Saleheen, Arnab Singh +8
X-ray beams with orbital angular momentum (OAM) are a promising tool for x-ray characterization techniques. Beams with OAM have a helicity--an azimuthally varying phase--which lead…
Switchable X-ray Orbital Angular Momentum from an Artificial Spin Ice
Justin Woods, Xiaoqian M Chen, Rajesh V. Chopdekar +12
Artificial spin ices (ASI) have been widely investigated as magnetic metamaterials with exotic properties governed by their geometries. In parallel, interest in X-ray photon orbita…
Chiral asymmetry detected in a 2D array of permalloy square nanomagnets using circularly polarized X ray Resonant Magnetic Scattering
J. Díaz, P. Gargiani, C. Quirós +8
The sensitivity of Circularly polarized X ray Resonant Magnetic Scattering (CXRMS) to chiral asymmetry has been demonstrated. The study was performed on a 2D array of Permalloy (Py…
Periodic chiral magnetic domains in single-crystal nickel nanowires
Jimmy J. Kan, Marko V. Lubarda, Keith T. Chan +4
We report on experimental and computational investigations of the domain structure of ~0.2 x 0.2 x 8 μm single-crystal Ni nanowires (NWs). The Ni NWs were grown by a thermal chemic…
Nanostructured complex oxides as a route towards thermal behavior in artificial spin ice systems
Rajesh V. Chopdekar, Binzhi Li, Thomas A. Wynn +8
We have used soft x-ray photoemission electron microscopy to image the magnetization of single domain LaSrMnO nano-islands arranged in geometrically frustrate…
Narrowly distributed crystal orientation in biomineral vaterite
Boaz Pokroy, Lee Kabalah Amitai, Iryna Polishchuk +6
Biominerals formed by animals provide skeletal support, and many other functions. They were previously shown to grow by aggregation of amorphous nanoparticles, but never to grow io…
