Giant anisotropic magnetoresistance with dual-four-fold symmetry in CaMnO3/CaIrO3 heterostructures
Suman Sardar, Megha Vagadia, Tejas Tank Sarmistha Das +9
The realization of four-fold anisotropic magnetoresistance (AMR) in novel 3d-5d heterostructures has boosted major efforts in antiferromagnetic spintronics. However, despite the po…
A Ballistic Graphene Cooper Pair Splitter
P. Pandey, R. Danneau, D. Beckmann
We report an experimental study of Cooper pair splitting in an encapsulated graphene based multiterminal junction in the ballistic transport regime. Our device consists of two tran…
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…
Ferromagnetism in CaRuO3 thin films by efficient route of tensile epitaxial strain
Shivendra Tripathi, Rakesh Rana, Parul Pandey +2
We show that a ferromagnetic (FM) order in the orthorhombic CaRuO3, which is a non-magnetic and iso-structural analog of FM system SrRuO3, can be established and stabilized by the…
