Giant X-ray circular dichroism in a time-reversal invariant altermagnet
Jun Okamoto, Ru-Pan Wang, Yen-Yi Chu +13
X-ray circular dichroism, arising from the contrast in X-ray absorption between opposite photon helicities, serves as a spectroscopic tool to measure the magnetization of ferromagn…
Atomic-scale visualization of surface-assisted orbital order
Howon Kim, Yasuo Yoshida, Chi-Cheng Lee +6
Orbital-related physics attracts growing interest in condensed matter research, but direct real-space access of the orbital degree of freedom is challenging. Here we report a first…
Carrier driven coupling in ferromagnetic oxide heterostructures
Ching-Hao Chang, Sujit Das, Sanjeev Kumar +1
Transition metal oxides are well known for their complex magnetic and electrical properties. When brought together in heterostructure geometries, they show particular promise for s…
3D Dirac cone carrier dynamics in Na3Bi and Cd3As2
G. S. Jenkins, C. Lane, B. Barbiellini +12
Optical measurements and band structure calculations are reported on 3D Dirac materials. The electronic properties associated with the Dirac cone are identified in the reflectivity…
Jahn-Teller distortion driven magnetic polarons in magnetite
H. Y. Huang, Z. Y. Chen, R. -P. Wang +11
The first known magnetic mineral, magnetite (FeO), has unusual properties which have fascinated mankind for centuries; it undergoes the Verwey transition at $\s…
Ultraquantum magnetoresistance in single-crystalline -AgSe
Chenglong Zhang, Haiwen Li, Tay-Rong Chang +9
In the history of condensed matter physics, reinvestigation of a well-studied material with enhanced quality sometimes led to important scientific discoveries. A well-known example…
