Temperature-Induced Magnonic Chern Insulator in Collinear Antiferromagnets
Yun-Mei Li, Xi-Wang Luo, Kai Chang
Thermal fluctuation in magnets will bring temperature-dependent self-energy corrections to the magnons, however, their effects on the topological orders of magnons is not well expl…
Nanoscale imaging of current density with a single-spin magnetometer
K. Chang, A. Eichler, C. L. Degen
Charge transport in nanostructures and thin films is fundamental to many phenomena and processes in science and technology, ranging from quantum effects and electronic correlations…
Spin Properties of Very Shallow Nitrogen Vacancy Defects in Diamond
B. K. Ofori-Okai, S. Pezzagna, K. Chang +7
We investigate spin and optical properties of individual nitrogen-vacancy centers located within 1-10 nm from the diamond surface. We observe stable defects with a characteristic o…
Spin current diode based on an electron waveguide with spin-orbit interaction
F. Zhai, K. Chang, H. Q. Xu
We propose a spin current diode which can work even in a small applied bias condition (the linear-response regime). The prototypal device consists of a hornlike electron waveguide…
Confined magnetic guiding orbit states
J. Reijniers, A. Matulis, K. Chang +2
We show how snake-orbit states which run along a magnetic edge can be confined electrically. We consider a two-dimensional electron gas (2DEG) confined into a quantum wire, subject…
