Ultrahigh Charge-to-Spin Conversion and Tunneling Magnetoresistance in Quasi-Two-Dimensional d-wave Altermagnet
Qing Zhang, Siyun Wang, Jianting Dong +1
The emergence of altermagnets has driven groundbreaking advances in spintronics. Notably, d-wave altermagnets support non-relativistic spin transport, efficient charge-to-spin conv…
Electron Doping Stabilization of Highly-Polar Supertetragonal BaSnO3
Qing Zhang, Karin M. Rabe, Xiaohui Liu
Could electrons stabilize ferroelectric polarization in unpolarized system? Basically, electron doping was thought to be contrary to polarization due to the well-known picture that…
Large magnon dichroism and other optical properties of hexagonal ferrite h-Lu0.6Sc0.4FeO3 with altermagnetic A2 spin ordering
V. A. Martinez, A. A. Sirenko, L. Bugnon +8
Multiferroic hexagonal h-Lu0.6Sc0.4FeO3 single crystals with non-collinear spins were studied using the THz and Raman scattering spectroscopies and ellipsometry. Antiferromagnetic…
Doping-induced Polyamorphic Transitions in Fluorite Oxides
Hao Yang, Qiaotong Luan, Qing Zhang +5
Fluorite oxides such as HfO exhibit rich and tunable phase behavior, making them promising candidates for next generation electronic devices. A key challenge is to design amorp…
Spin dynamics and magnetic excitations of quasi-1D spin chain CaZnMnO
Suheon Lee, D. T. Adroja, Qing Zhang +7
To reveal the structure-property relationship in quasi-one-dimensional (1D) spin-chain system CaZnMnO, we present comprehensive results, combining basic physical characteri…
