Hidden orbital polarization in diamond, silicon, germanium, gallium arsenide and layered materials
Ji Hoon Ryoo, Cheol-Hwan Park
It was previously believed that the Bloch electronic states of non-magnetic materials with inversion symmetry cannot have finite spin polarizations. However, since the seminal work…

Ising-Type Magnetic Ordering in Atomically Thin FePS3
Jae-Ung Lee, Sungmin Lee, Ji Hoon Ryoo +6
Magnetism in two-dimensional materials is not only of fundamental scientific interest but also a promising candidate for numerous applications. However, studies so far, especially…

Spin-conserving and reversing photoemission from the surface states of BiSe and Au (111)
Ji Hoon Ryoo, Cheol-Hwan Park
We present a theory based on first-principles calculations explaining (i) why the tunability of spin polarizations of photoelectrons from BiSe (111) depends on the band ind…
