The Landau-Lifshitz-Bloch equation for domain wall motion in antiferromagnets
Z. Y. Chen, Z. R. Yan, M. H. Qin +1
In this work, we derive the Landau-Lifshitz-Bloch equation accounting for the multi-domain antiferromagnetic (AFM) lattice at finite temperature, in order to investigate the domain…
Thickness-Dependent Differential Reflectance Spectra of Monolayer and Few-Layer MoS2, MoSe2, WS2 and WSe2
Yue Niu, Sergio Gonzalez-Abad, Riccardo Frisenda +12
The research field of two dimensional (2D) materials strongly relies on optical microscopy characterization tools to identify atomically thin materials and to determine their numbe…
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…
Isotropic non-local Gilbert damping driven by spin currents in epitaxial Pd/Fe/MgO(001) films
Yan Li, Yang Li, Qian Liu +7
Although both theoretical predications and experimental observations demonstrated that the damping factor is anisotropic at ferromagnet/semiconductor interface with robust interfac…
Direct observation of ferroelectricity in CaMnO and its prominent light absorption
Meifeng Liu, Yang Zhang, Ling-Fang Lin +10
Layered perovskites O are known to exhibit the so-called hybrid improper ferroelectricity. Despite experimentally confirmed cases (e.g. nonmagnetic =Ti and Sn), the…
Structural transitions in hybrid improper ferroelectric CaTiO tuned by site-selective iso-valent substitutions: a first-principles study
C. F. Li, S. H. Zheng, H. W. Wang +8
CaTiO is an experimentally confirmed hybrid improper ferroelectric material, in which the electric polarization is induced by a combination of the coherent TiO octa…
