Enhancement of giant magnetoelectric effect in Ni-doped CaBaCo${}_4$O${}_7$

M. Gen, A. Miyake, H. Yagiuchi +6

The polar magnet CaBaCo${}_4$O${}_7$ is known to exhibit the largest magnetic-field-driven electric polarization change ($\Delta P$) associated with an antiferromagnetic (AFM)-ferrimagne…
