Electrical control of large magnetization reversal in a helimagnet
Yi Sheng Chai, Sangil Kwon, Sae Hwan Chun +4
In spite of both technical and fundamental importance, reversal of a macroscopic magnetization by an electric field (E) has been limitedly realized and remains as one of great chal…
Electric field control of nonvolatile four-state magnetization at room temperature
Sae Hwan Chun, Yi Sheng Chai, Byung-Gu Jeon +11
We find the realization of large converse magnetoelectric (ME) effects at room temperature in a multiferroic hexaferrite BaSrCoFeO single crys…
Realization of giant magnetoelectricity in helimagnets
Sae Hwan Chun, Yi Sheng Chai, Yoon Seok Oh +9
We show that low field magnetoelectric (ME) properties of helimagnets Ba0.5Sr1.5Zn2(Fe1-xAlx)12O22 can be efficiently tailored by Al-substitution level. As x increases, the critica…
Low-magnetic-field control of dielectric constant at room temperature realized in Ba0.5Sr1.5Zn2Fe12O22
Y S Chai, S H Chun, S Y Haam +3
We show that room temperature resistivity of Ba0.5Sr1.5Zn2Fe12O22 single crystals increases by more than three orders of magnitude upon being subjected to optimized heat treatments…
