    • Abstract


      We report on the increase in spin re-orientation transition temperature (T$_{SR}$) and Neel temperature (T$_N$) in Nd$_{0.95}$Gd$_{0.05}$FeO$_3$ compound, by substituting Gd$^{3+}$ ions at the A-site of NdFeO$_3$. Structural and magnetic properties ofNd$_{1-x}$Gd$_x$FeO$_3$ (x = 0, 0.03 and 0.05 mol%) have been analysed by employing solid-state reaction method. Crystallite size reduction and lattice contraction have been observed with increase in Gd substitution in NdFeO$_3$. $M–H$ curves depictstrong ferromagnetic behaviour of Nd$_{1-x}$Gd$_x$FeO$_3$ with a non-saturating and large coercive hysteresis loops. The crystallite size of Nd$_{1-x}Gd$_x$FeO$_3$ influences the magnetic property, resulting in the ferromagnetic behaviour with higher M and Hc values at room temperature and low temperatures
