The magnetization reversal process is an intrinsic property of NdMn_0.8Fe_0.2O${}_3$ single crystal below $T_{\mathrm{N}}$ = 59.5 K for magnetization field-cooled regime. The phenomenon is very anisotropic and a negative magnetization was observed below the compensation temperature $T_{\mathrm{Comp}}$ = 21.7(1) K; 25.9(1) K and 22.7(1) K for $a$-; $b$- and $c$-axis and field 0.01 T. Magnetocrystalline anisotropy results in different shape of hysteresis loop for any crystallographic orientation below $T_{\mathrm{N}}$. Ferromagnetic behavior, attributed to ordering of Nd sublattice, with coercive field of 1.32 T at temperature $T$ = 2 K is typical for magnetic field applied along $b$-axis. Signature of ferromagnetic ordering exists even at 30 K. Very low hysteresis was observed in $a$–$c$ plane and the $a$-axis magnetization loop has butterfly shape. A model of two Nd and Mn interpenetrating magnetic sublattices describes magnetization reversal better than a cluster model.

磁化反转过程是 NdMn _0.8 Fe _0.2 O的固有特性${}_3$ 下面是单晶 ${吨}_{\mathrm{N}}$= 59.5 K 用于磁化场冷却状态。这种现象非常各向异性，在补偿温度以下观察到负磁化${吨}_{\mathrm{比较}}$= 21.7(1) K; 25.9(1) K 和 22.7(1) K 对于$\mathrm{一种}$-; $乙$- 和 $C$轴和场 0.01 T。磁晶各向异性导致以下任何晶体取向的磁滞回线形状不同 ${吨}_{\mathrm{N}}$. 铁磁行为，归因于 Nd 亚晶格的排序，在温度下具有 1.32 T 的矫顽场$吨$ = 2 K 是沿施加磁场的典型值 $乙$-轴。即使在 30 K 下也存在铁磁有序的特征。在$\mathrm{一种}$——$C$ 飞机和 $\mathrm{一种}$-轴磁化回路呈蝶形。两个 Nd 和 Mn 互穿磁性亚晶格的模型比集群模型更好地描述了磁化反转。
