Gate-tunable heavy fermions in a moiré Kondo lattice

Kavli Affiliate: Jie Shan | First 5 Authors: Wenjin Zhao, Bowen Shen, Zui Tao, Zhongdong Han, Kaifei Kang | Summary: The Kondo lattice, describing a matrix of local magnetic moments coupled via spin-exchange interactions to itinerant conduction electrons, is a prototype of strongly correlated quantum matter. Traditionally, Kondo lattices are realized in intermetallic compounds containing […]

Emergence of Layer Stacking Disorder in c-axis Confined MoTe$_2$

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: James L Hart, Lopa Bhatt, Yanbing Zhu, Myung-Geun Han, Elisabeth Bianco | Summary: The layer stacking order in 2D materials strongly affects functional properties and holds promise for next generation electronic devices. In bulk, octahedral MoTe$_2$ possesses two stacking arrangements, the Weyl semimetal T$_d$ phase, and […]

Interplay of Hidden Orbital Order and Superconductivity in CeCoIn5

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Weijiong Chen, Clara Neerup Breiø, Freek Massee, M. P. Allan, C. Petrovic | Summary: Visualizing atomic-orbital degrees of freedom is a frontier challenge in scanned microscopy. Some types of orbital order are virtually imperceptible to normal scattering techniques because they do not reduce the overall […]

Strong variation of spin-orbit torques with relative spin relaxation rates in ferrimagnets

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Lijun Zhu, Daniel C Ralph, , , | Summary: Spin-orbit torques (SOTs) have been widely understood as an interfacial transfer of spin that is independent of the bulk properties of the magnetic layer. Here, we report that SOTs acting on ferrimagnetic FexTb1-x layers decrease and vanish […]

A minimal model of solitons in nematic liquid crystals

Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Noe Atzin, Ali Mozaffari, Xingzhou Tang, Soumik Das, Nicholas L. Abbott | Summary: Solitons in liquid crystals have generated considerable interest. Several hypotheses of varying complexity have been advanced to explain how they emerge, and a consensus has not emerged yet about the underlying forces responsible […]

Periodic Artifact Reduction in Fourier transforms of Full Field Atomic Resolution Images

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Robert Hovden, Yi Jiang, Huolin L. Xin, Lena F. Kourkoutis, | Summary: The discrete Fourier transform is among the most routine tools used in high-resolution scanning / transmission electron microscopy (S/TEM). However, when calculating a Fourier transform, periodic boundary conditions are imposed and sharp discontinuities between […]

Current-induced switching of thin film $α$-Fe$_2$O$_3$ devices imaged using a scanning single-spin microscope

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Qiaochu Guo, Anthony D’Addario, Yang Cheng, Jeremy Kline, Isaiah Gray | Summary: Electrical switching of N’eel order in an antiferromagnetic insulator is desirable as a basis for memory applications. Unlike electrically-driven switching of ferromagnetic order via spin-orbit torques, electrical switching of antiferromagnetic order remains poorly understood. […]

Liquid Crystals as Multifunctional Interfaces for Trapping and Characterizing Microplastics

Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Fiona Mukherjee, Anye Shi, Xin Wang, Fengqi You, Nicholas L. Abbott | Summary: Identifying and removing microplastics (MPs) from the environment is a global challenge. This study explores how the colloidal fraction of common MPs behave at aqueous interfaces of liquid crystal (LC) films. We observed […]
