Intrinsic spin Hall torque in a moire Chern magnet

Kavli Affiliate: Jie Shan | First 5 Authors: C. L. Tschirhart, Evgeny Redekop, Lizhong Li, Tingxin Li, Shengwei Jiang | Summary: In spin torque magnetic memories, electrically actuated spin currents are used to switch a magnetic bit. Typically, these require a multilayer geometry including both a free ferromagnetic layer and a second layer providing spin […]

Incorporating tunability into a universal scaling framework for shear thickening

Kavli Affiliate: Itai Cohen | First 5 Authors: Meera Ramaswamy, Itay Griniasty, James P Sethna, Bulbul Chakraborty, Itai Cohen | Summary: Recently, we proposed a universal scaling framework that shows shear thickening in dense suspensions is governed by the crossover between two critical points: one associated with frictionless isotropic jamming and a second corresponding to […]

Reentrant Rigidity Percolation in Structurally Correlated Filamentous Networks

Kavli Affiliate: Itai Cohen | First 5 Authors: Jonathan Michel, Gabriel von Kessel, Thomas Wyse Jackson, Lawrence J. Bonassar, Itai Cohen | Summary: Many biological tissues feature a heterogeneous network of fibers whose tensile and bending rigidity contribute substantially to these tissues’ elastic properties. Rigidity percolation has emerged as a important paradigm for relating these […]

A puzzling insensitivity of magnon spin diffusion to the presence of 180$^circ$ domain walls in a ferrimagnetic insulator

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Ruofan Li, Lauren J. Riddiford, Yahong Chai, Minyi Dai, Hai Zhong | Summary: We present room-temperature measurements of magnon spin diffusion in epitaxial ferrimagnetic insulator MgAl$_{0.5}$Fe$_{1.5}$O$_{4}$ (MAFO) thin films near zero applied magnetic field where the sample forms a multi-domain state. Due to a weak uniaxial […]
