Hydrogen-induced tunable remanent polarization in a perovskite nickelate
Yifan Yuan, Michele Kotiuga, Tae Joon Park +18
Materials with field-tunable polarization are of broad interest to condensed matter sciences and solid-state device technologies. Here, using hydrogen (H) donor doping, we modify t…
Mapping of Spin-Wave Transport in Thulium Iron Garnet Thin Films Using Diamond Quantum Microscopy
Rupak Timalsina, Haohan Wang, Bharat Giri +3
Spin waves, collective dynamic magnetic excitations, offer crucial insights into magnetic material properties. Rare-earth iron garnets offer an ideal spin-wave (SW) platform with l…
Giant interfacial spin-Hall angle from Rashba-Edelstein effect revealed by the spin-Hall Hanle processes
Jing Li, Andrew H. Comstock, Aeron McConnell +2
The Rashba-Edelstein effect (REE), which generates interfacial spin polarization and subsequent spin current, is a compelling spin-charge conversion mechanism for spintronics appli…
Dual mechanisms for transient capacitance anomaly in improper ferroelectrics
Xin Li, Yu Yun, Pratyush Buragohain +6
The recent discovery of transient negative capacitance has sparked an intense debate on the role of homogeneous and inhomogeneous mechanisms in polarizations switching. In this wor…
Berry Curvature and Topological Hall Effect in Magnetic Nanoparticles
Ahsan Ullah, Balamurugan Balasubramanian, Bibek Tiwari +4
Analytical calculations and micromagnetic simulations are used to determine the Berry curvature and topological Hall effect (THE) due to conduction electrons in small ferromagnetic…
Interfacial and Surface Magnetism in Epitaxial NiCo2O4(001)/MgAl2O4 Films
Corbyn Mellinger, Xiao Wang, Arjun Subedi +6
NiCo2O4 (NCO) films grown on MgAl2O4 (001) substrates have been studied using magnetometry, x-ray magnetic circular dichroism (XMCD) based on x-ray absorption spectroscopy, and spi…
Improper ferroelectricity in ultrathin hexagonal ferrites film
Xin Li, Yu Yun, Xiaoshan Xu
The suppression of ferroelectricity in ultrathin films of improper ferroelectric hexagonal ferrites or manganites has been attributed to the effect of interfacial clamping, however…
Intrinsic Exchange Bias from Interfacial Reconstruction in an Epitaxial NixCoyFe3-x-yO4(111)/α-Al2O3(0001) Thin Film Family
Detian Yang, Yaohua Liu, Xiaoshan Xu
Intrinsic exchange bias is known as the unidirectional exchange anisotropy that emerges in a nominally single-component ferro-(ferri-)magnetic system. In this work, with magnetic a…
