采用简单的溶液法合成了单相纳米晶YFeO_3。平均粒径为42.2nm。该粒子在10-300 K温度范围内表现出铁磁行为，矫顽力为23 kOe。在2-300 K温度范围内，磁化强度随温度的变化服从Bloch方程，Bloch常数为9.98 × 10 ~（-6）K ~（-3）/2。在300 K温度下观察到铁磁磁滞回线。在10 K时，场冷样品显示出交换偏置场。(C)2009爱思唯尔有限公司版权所有。
Single phase nanocrystalline YFeO3 has been synthesized by a simple solution method. The average particle diameter is 42.2 nm. The particles exhibit ferromagnetic behaviour in the temperature range 10-300 K with a coercivity of 23 kOe. The magnetization versus temperature over the temperature range 2-300 K obeys Bloch equation with a Bloch constant value 9.98 x 10(-6) K-3/2. Ferromagnetic hysteresis loops have been observed up to a temperature of 300 K. At 10 K a field-cooled sample shows an exchange bias field. (C) 2009 Elsevier B.V. All rights reserved.
