• Effect of chemical pressure and R–Mn interaction on the magnetic structure of h-YMnO3.
• Anomalous reduction in volume at TN, correlated with square of AFM moment.
• A spin reorientation behavior is observed on decreasing
• Additional interaction between the doped R and Mn influences the magnetic structure in the case of Ho and Tb doped samples.
In this report the combined effects of chemical pressure and R–Mn interaction on the structural and magnetic properties of frustrated h-YMnO3 have been investigated. Towards this, neutron powder diffraction and magnetization measurements were carried out on isostructural compounds Y1−xRxMnO3(R=Yb, Er, Tb, Ho; x≤0.2) with hexagonal structure (P63cm space group). The dopants are evenly distributed between the two Yttrium sites. The unit cell volume shows a linear increase with average A-site ionic radii,
