Antiferromagnetic VdW Phase at the Interface of Sputtered Topological Insulator/Ferromagnet-Bi2Te3/Ni80Fe20 Heterostructures
Nirjhar Bhattacharjee, Krishnamurthy Mahalingam, Adrian Fedorko +11
Magnetic ordering in topological insulators (TI) is crucial for breaking time-reversal symmetry (TRS) and thereby opening a gap in the topological surface states (TSSs) [1-6], whic…
Evaluation of carbon incorporation in sulfide thin films grown by hybrid pulsed laser deposition
Claire Wu, Mythili Surendran, Shin Muramoto +2
Vapor-pressure-mismatched materials, such as transition metal chalcogenides, have emerged as key electronic, photonic, and quantum materials. Hybrid pulsed laser deposition (hPLD)…
Exchange-biased quantum anomalous Hall effect
Peng Zhang, Purnima P. Balakrishnan, Christopher Eckberg +12
The quantum anomalous Hall (QAH) effect is characterized by a dissipationless chiral edge state with a quantized Hall resistance at zero magnetic field. Manipulating the QAH state…
Elucidating proximity magnetism through polarized neutron reflectometry and machine learning
Nina Andrejevic, Zhantao Chen, Thanh Nguyen +7
Polarized neutron reflectometry is a powerful technique to interrogate the structures of multilayered magnetic materials with depth sensitivity and nanometer resolution. However, r…
Electrical switching of the perpendicular Neel order in a collinear antiferromagnet
Wenqing He, Tianyi Zhang, Yongjian Zhou +17
Electrical manipulation of magnetic order by current-induced spin torques lays the foundation for spintronics. One promising approach is encoding information in the Néel vector of…
Polarized Neutron Reflectometry Study of Depth Dependent Magnetization Variation in Co Thin Film on a PMN-PT Substrate
Md Mamun Al-Rashid, Alexander Grutter, Brian Kirby +1
We studied the depth dependent magnetization profile of the magnetostrictive Co thin film layer in a PMN-PT (011)/Ta/Co/Ta structure under both zero and nonzero applied electric fi…
Emergent electric field control of phase transformation in oxide superlattices
Di Yi, Yujia Wang, Olaf M. J. van 't Erve +13
Electric fields can transform materials with respect to their structure and properties, enabling various applications ranging from batteries to spintronics. Recently electrolytic g…
Exploring interfacial exchange coupling and sublattice effect in heavy metal/ferrimagnetic insulator heterostructures using Hall measurements, x-ray magnetic circular dichroism, and neutron reflectometry
Qiming Shao, Alexander Grutter, Yawen Liu +13
We use temperature-dependent Hall measurements to identify contributions of spin Hall, magnetic proximity, and sublattice effects to the anomalous Hall signal in heavy metal/ferrim…
