Electric Polarization Induced by Néel Order without Magnetic Superlattice: Experimental Study of Cu3Mo2O9 and Numerical Study of a Small Spin Cluster
Haruhiko Kuroe,T. Hosaka,S. Hachiuma,Tomoyuki Sekine,M. Hase,Kunihiko Oka,Toshimitsu Ito,Hiroshi Eisaki,Masashi Fujisawa,Susumu Okubo,Hitoshi Ohta +10 more
TL;DR: In this paper, the antiferromagnetic order in the distorted tetrahedral quasi-one-dimensional spin system induces electric polarization, and the effects of low dimensionality and magnetic frustration are expected to appear simultaneously.

TL;DR: In this paper, the multiferroic properties in the distorted tetrahedral quasi-one dimensional spin system were studied and the antiferromagnetic order was formed together with ferroelectric properties at 7.9$ K under zero magnetic field and obtained the magnetic-field-temperature phase diagram by measuring dielectric constant and spontaneous electric polarization.
