dc.description.abstract
Manipulating magnetic moments by electric fields has been an everlasting goal for fundamental research. Recently, we could demonstrate a peculiar magnetoelectric behavior in multiferroic GdMn2O5 showing a switching through a cycle of four states when the magnetic field is ramped up and down. In this sequence, half of the spins undergo a rotation of about 90° each time the magnetic field is ramped leading to a full-circle 360° rotation when applying and removing a magnetic field two times in a series. GdMn2O5 thus acts as a magnetic crankshaft that converts the back-and-forth variations of the magnetic field into a circular spin motion. This peculiar four-state magnetoelectric switching emerges as a topologically protected boundary between two different series, 1→2→3→4→1 and 1→4→3→2→1, respectively.Further on, in a certain range of experimental parameters the 4-state sequence becomes topologically trivial. In this regime, the external electric field adds a key parameter of the switching. We show that in such case the electric voltage allows a full control over the four magnetoelectric states in GdMn2O5
