Spin Distribution (IMAGE) Science China Press Caption The change of spin distribution and bandstructure upon FE switching for (a) Cu2(CrS2)3 and (b) Cu3(CrS2)4. Black and red arrows in the sketches of M-E loops denote the direction of polarization and magnetization, respectively. The smaller net magnetization marked by shorter red arrow in (b) is mainly attributed to the reduction in the magnetic moment of the top layer compared with other layers (left), which is "transferred" to the bottom of different spin direction after FE switching (right). Black and red lines in bandstructures denote spin-up and spin-down channel, respectively. Credit ©Science China Press Usage Restrictions Use with credit.
