Topological Hall effect in single thick SrRuO3 layers induced by defect engineering
Changan Wang, Ching-Hao Chang, Andreas Herklotz +11
The topological Hall effect (THE) has been discovered in ultrathin SrRuO3 (SRO) films, where the interface between the SRO layer and another oxide layer breaks the inversion symmet…
Defect-induced exchange bias in a single SrRuO3 layer
Changan Wang, Chao Chen, Ching-Hao Chang +9
Exchange bias stems from the interaction between different magnetic phases and therefore it generally occurs in magnetic multilayers. Here we present a large exchange bias in a sin…
Tunable disorder and localization in the rare-earth nickelates
Changan Wang, Ching-Hao Chang, Angus Huang +13
The rare-earth nickelates are a rich playground for transport properties, known to host non-Fermi liquid character, resistance saturation and metal-insulator transitions. We report…
Carrier driven antiferromagnetism and exchange-bias in SrRuO3/CaRuO3 heterostructures
Parul Pandey, Ching-Hao Chang, Angus Huang +7
Oxide heterostructures exhibit a rich variety of magnetic and transport properties which arise due to contact at an interface. This can lead to surprising effects that are very dif…
Angle-dependent Weiss oscillations in a nanocorrugated two-dimensional electron gas
Ching Hao Chang, Carmine Ortix
We investigate the diffusive magnetotransport properties of a two-dimensional electron gas residing in a wrinkled nanostructure. The curved geometry of the nanostructure renders an…
Spin-glass-like behavior caused by Mn-rich Mn(Ga)As nanoclusters in GaAs
Ching-Hao Chang, T. M. Hong
We simulate the indirect exchange interaction between Mn-rich Mn(Ga)As nanoclusters in GaAs by analytical means. In contrast to the conventional Ruderman-Kittel-Kasuya-Yosida (RKKY…
