Observation of High-Order Anisotropic Magnetoresistance in a Cubic Ferromagnet
Haoran Chen, Yue Chen, Yizi Feng +10
High-order anisotropic magnetoresistance (AMR) is observed up to the 18th harmonic in cubic Fe(001) thin films, overturning the long-standing paradigm that only two- and four-fold…

Symmetry-forbidden intraband transitions leading to ultralow Gilbert damping in van der Waals ferromagnets
Weizhao Chen, Yu Zhang, Yi Liu +1
Based upon first-principles calculations, we report ultralow Gilbert damping in two-dimensional (2D) van derWaals (vdW) ferromagnets. The low damping occurs at weak scattering beca…

Orbital-excitation-dominated magnetization dissipation and quantum oscillation of Gilbert damping in Fe films
Yue Chen, Haoran Chen, Xi Shen +4
Using first-principles electronic structure calculation, we demonstrate the spin dissipation process in bulk Fe by orbital excitations within the energy bands of pure spin characte…
