Universal Design Principles for High-Quality Persistent Spin Textures
Cheng-Ao Ji, Lingling Tao, James M. Rondinelli +1
Persistent spin texture (PST) describes a unique spin-momentum locking in momentum space that maintains a uniform spin orientation through portions of the Brillouin zone (BZ), enab…
Design and theory of switchable linear magnetoelectricity by ferroelectricity in Type-I multiferroics
Hui-Min Zhang, Cheng-Ao Ji, Tong Zhu +5
We present a comprehensive theoretical investigation of magnetoelectric (ME) coupling mechanisms in 19 altermagnetic and 4 ferrimagnetic Type-I multiferroics using electronic band…
Piezomagnetism-driven magnetoelectric coupling in altermagnetic multiferroic K3Cr2F7
Ying Zhou, Hui-Min Zhang, Cheng-Ao Ji +4
Ferroelectric control of altermagnetism in momentum space has been studied widely, while the control of magnetism in real space of altermagnets are still rare. We present a design…
Out-of-plane ferroelectricity, magnetoelectric coupling and persistent spin texture in two-dimensional multiferroics
Ying Zhou, Cheng-Ao Ji, Shuai Dong +1
Two dimensional multiferroics with out of plane ferroelectricity hold significant promise for miniaturized magnetoelectric spin-orbit transistors, yet systems combining robust ferr…
