Abstract: The optical and magnetic properties of nano-LaFeO3 powders prepared by a starchassisted soft-chemistry synthesis and corresponding ceramics have been investigated.Magnetic measurements on LaFeO3 powders with crystallite sizes of 37−166 nm showpronounced magnetization hysteresis loops. Measurements at 300 K reveal that the coercivity(Hc) of 19−32 kOe depends on the crystallite size, whereas the low remanence values (Mr) ofroughly 0.2 emu/g and the maximal magnetization (Mmax) at 90 kOe of 1.05−0.85 emu/g areonl…
