Abstract

We have made thermal expansion and neutron-diffraction studies of YMnOs, and found that our bulk measurements showed anomalous behavior at TN = 80 K. The analysis of the neutron-diffraction data shows that the magnetic scattering of YMnO₃ can be described equally well by the Γ₁ and Γ₃ representations of space group P6₃cm. Around the Néel temperature, we also find that the lattice constants change anomalously, implying the existence of a magneto-electric effect.
