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…
CuBr2-A New Multiferroic Material with High Critical Temperature
L. Zhao, T. L. Hung, C. C. Li +10
A new multiferroic material, CuBr2, is reported for the first time. CuBr2 has not only a high transition temperature (close to liquid nitrogen temperature) but also low dielectric…
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…
Evidence for Coexistence of Superconductivity and Magnetism in Single Crystals of Co-doped SrFeAs
Jun Sung Kim, Seunghyun Khim, Liqin Yan +5
In order to investigate whether magnetism and superconductivity coexist in Co-doped SrFeAs, we have prepared single crystals of SrFeCoAs, = 0 and 0.4, a…
Vortex-glass phase transition and superconductivity in an under- doped (Ba,K)Fe2As2 single crystal
Hyeong-Jin Kim, Yong. Liu, Yoon Seok Oh +4
Measurements of magnetotransport and current-voltage (I-V) characteristics up to 9 T were used to investigate the vortex phase diagram of an under-doped Measurements of magnetotran…
