Designing the flow properties of concentrated particle suspensions

Abhinendra Singh (University of Chicago), Christopher Ness (University of Edinburgh), Ryohei Seto (Wenzhou Institute, University of Chinese Academy of Sciences), Juan J de Pablo (University of Chicago), Heinrich M Jaeger (University of Chicago)
In a concentrated suspension of small solid particles in a liquid under shear, a large number of dynamically evolving particle-particle and particle-liquid interfaces controls the overall flow properties.

Pure Spin Current in a Non-Equilibrium Magnetic Insulator

X. Li, G. Fiete, J. Zhou: Univ. of Texas at Austin
We investigate spin current in a magnetic insulator, YIG, under thermally driven  non-equilibrium conditions, a challenging task for conventional transport techniques.

MEM-C IRG-2: An atomically thin in-plane layered antiferromagnetic insulator

X. Cai*, T. Song, N. P. Wilson, G. Clark, M. He, X. Zhang, T. Taniguchi, K. Watanabe, W. Yao, D. Xiao, M. A., McGuire, D. Cobden*, X .Xu* *MEM-C participants
We investigate the magnetic order of atomically thin CrCl3 by employing vertical tunneling measurements, which are sensitive to the relative alignment of spins in different layers.

I-MRSEC educational web series: “Magnetic Fields”

In Summer 2019 the I-MRSEC officially released the web series “Magnetic Fields,” which follows middle school aged characters as they encounter a new material at the I-MRSEC, and emphasizes the scientific process, persistence, and the diversity of scientists. The episodes include “Behind the science,” featuring interviews with I-MRSEC researchers sharing their paths in science and advice to those interested in STEM studies.

Ultrasoft, Slip Mediated Bending of Multilayer Graphene

Two-dimensional (2D) materials like graphene are highly deformable due to their atomically thin structure. To fabricate deformable devices (e.g. flexible and wearable electronics) that capitalize on their ultrasoft nature, it is critical to assess the bending stiffness of graphene.

Discovery of a hexagonal easy-plane metallic antiferromagnet in the CuMnAs system

Daniel Shoemaker and Andre Schleife University of Illinois at Urbana-Champaign
We discovered a new hexagonal metallic antiferromagnetic phase in the Cu-Mn-As system.   Electrical switching and read-out of tetragonal CuMnAs inspired a world-wide research effort in metallic antiferromagnets. Phase equilibria in this system (Fig. a) however is poorly understood.
