First-principles Study of Spiral Spin Density Waves in Monolayer MnCl Using Generalized Bloch Theorem
Teguh Budi Prayitno, Fumiyuki Ishii
We investigated the spiral spin density waves in the monolayer 1T-MnCl for a set of spiral vectors based on first-principles calculations. The magnetic ground states were evalu…
Intrinsic persistent spin helix in two-dimensional group-IV monochalcogenide MX (M : Sn, Ge; X: S, Se, Te) monolayer
Moh. Adhib Ulil Absor, Fumiyuki Ishii
Energy-saving spintronics are believed to be implementable on the systems hosting persistent spin helix (PSH) since they support an extraordinarily long spin lifetime of carriers.…
Carrier-induced Antisymmetric-symmetric Tendencies of Spin Stiffness in Zigzag Graphene Nanoribbons
Teguh Budi Prayitno, Fumiyuki Ishii
The generalized Bloch theorem was applied to calculate the spin stiffness and to consider its tendencies when introducing the doping in zigzag graphene nanoribbons. To reach the in…
Electric-field-induced Z2 topological phase transition in strained single bilayer Bi(111)
Hikaru Sawahata, Naoya Yamaguchi, Fumiyuki Ishii
For controlling the critical electric fields of the topological phase transition in single bilayer Bi(111), we investigated topological phases in a strained system through first-pr…
First-principles Study of Spin-wave Excitations of 3 Transition Metals with Linear Combination of Pseudo-atomic Orbitals
Teguh Budi Prayitno, Fumiyuki Ishii
We have employed the generalized Bloch theorem to evaluate the spin stiffness constants of 3 transition metals (bcc-Fe, fcc-Co, and fcc-Ni) within the linear combination of pseu…
Photoinduced Rashba spin to charge conversion via interfacial unoccupied state
Jorge Puebla, Florent Auvray, Naoya Yamaguchi +5
At interfaces with inversion symmetry breaking, Rashba effect couples the motion of electrons to their spin; as a result, spin-charge interconversion mechanism can occur. These int…
