Quantum spin liquid on a 3D bipartite lattice of spin trimers stabilized by enhanced effective anisotropy
M. Gomilšek, L. Mangin-Thro, T. Arh +22
Quantum spin liquids (QSLs) represent highly entangled states of matter in which frustration-induced quantum fluctuations suppress any symmetry-breaking phase transition down to ab…
Quantitative measurements of size-dependent magnetoelectric coupling in Fe3O4 nanoparticles
Kyongjun Yoo, Byung-Gu Jeon, Sae Hwan Chun +6
Bulk magnetite (Fe3O4), the loadstone used in magnetic compasses, has been known to exhibit magnetoelectric (ME) properties below ~10 K; however, corresponding ME effects in Fe3O4…
X-ray scattering study of pyrochlore iridates: crystal structure, electronic and magnetic excitations
J. P. Clancy, H. Gretarsson, E. K. H. Lee +12
We have investigated the structural, electronic, and magnetic properties of the pyrochlore iridates Eu2Ir2O7 and Pr2Ir2O7 using a combination of resonant elastic x-ray scattering,…
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…
Enhanced Upper Critical Fields in a New Quasi-one-dimensional Superconductor Nb2PdxSe5
Seunghyun Khim, Bumsung Lee, Ki-Young Choi +9
We report a discovery of superconductivity with Tc = 5.5 K in Nb2PdxSe5, in which one-dimensional (1D) Nb-Se chains existing along the b-direction hybridize each other to form the…
PbCu3TeO7: An S=1/2 staircase Kagome lattice with significant intra- and inter-plane couplings
B. Koteswararao, R. Kumar, Jayita Chakraborty +5
We have synthesized polycrystalline and single crystal samples of PbCu3TeO7 and studied its properties via magnetic susceptibility chi(T) and heat-capacity Cp(T) measurements and a…
Theoretical Modeling of ME effect at Low frequency and Resonance Frequency for Magnetoelectric Laminates with Anisotropic Piezoelectric Properties
Deepak Rajaram Patil, Yisheng Chai, Rahul C. Kambale +11
A new theory is developed for the magnetoelectric (ME) coupling in a symmetric 2-2 ME laminate having a representative piezoelectric crystal (PMN-PT) particularly with anisotropic…
Topological states in pyrochlore iridates: long-range anisotropy strongly competing with spin-orbit interaction
Liviu Hozoi, H. Gretarsson, J. P. Clancy +7
In the search for topological phases in correlated electron systems, iridium-based pyrochlores A2Ir2O7 -- materials with 5d transition-metal ions -- provide fertile grounds. Severa…
Physical properties of transparent perovskite oxides (Ba,La)SnO3 with high electrical mobility at room temperature
Hyung Joon Kim, Useong Kim, Tai Hoon Kim +9
Transparent electronic materials are increasingly in demand for a variety of optoelectronic applications. BaSnO3 is a semiconducting oxide with a large band gap of more than 3.1 eV…
High Mobility in a Stable Transparent Perovskite Oxide
Hyung Joon Kim, Useong Kim, Hoon Min Kim +8
We discovered that La-doped BaSnO3 with the perovskite structure has an unprecedentedly high mobility at room temperature while retaining its optical transparency. In single crysta…
