Nanostructured HoFeO₃ powders were obtained by solution combustion method at various glycine-nitrate ratios (G/N = 0.2, 0.4, …, 1.4). According to X-ray powder diffractometry data, the presence of two modifications of HoFeO₃ in the synthesized samples was established: orthorhombic (Pbnm) and hexagonal (P6₃/mmc). The crystallite size of the obtained compositions varies from 62 ± 6 to 29 ± 3 nm, depending on the G/N ratio. From magnetic structure studies, it is found that HoFeO₃ obtained with a stoichiometric amount of glycine in the reaction solution is in the magnetically ordered state and is represented by a sextet with quadrupole splitting (QS) = 0 mm/s, isomeric shift (IS) = 0.36 mm/s and effective field strength (H_eff) = 497 kOe. According to the results of vibrational magnetometry, it is found that the orthoferrites obtained have a ferromagnetic structure, the main parameters of which (M_s, M_r and H_c) systematically change with a change in the redox ratio of the reaction mixture and, as a consequence, their phase composition, and reach maximum values at a G/N ratio = 0.6. In the samples obtained with a significant excess and lack of glycine (G/N = 0.2 and 1.4), despite their amorphous nature, hysteresis loops characteristic of the ferromagnetic state of the substance is observed. It is hopeful to obtain a pure hexagonal modification of HoFeO₃ via heat treatment on amorphous products of glycine-nitrate combustion.

纳米结构的HoFeO ₃粉末通过溶液燃烧法在不同的甘氨酸-硝酸盐比（G/N = 0.2, 0.4, ..., 1.4）下获得。根据 X 射线粉末衍射数据，确定合成样品中存在两种 HoFeO ₃变体：正交（Pbnm）和六方（P 6 ₃ / mmc）。所得组合物的微晶尺寸从 62 ± 6 到 29 ± 3 nm 不等，具体取决于 G/N 比。由磁结构研究发现，HoFeO ₃在反应溶液中用化学计量的甘氨酸获得的处于磁性有序状态，并由四极分裂 (QS) = 0 mm/s、异构位移 (IS) = 0.36 mm/s 和有效场强的六重峰表示 ( H _eff ) = 497 kOe。根据振动磁力测量结果发现，所得正铁氧体具有铁磁结构，其主要参数为（M _s、M _r和H _c) 随着反应混合物的氧化还原比的变化以及它们的相组成的变化而系统地变化，并在 G/N 比 = 0.6 时达到最大值。在显着过量和缺乏甘氨酸（G/N = 0.2 和 1.4）的样品中，尽管它们具有无定形性质，但仍观察到物质铁磁状态的磁滞回线特征。通过对甘氨酸-硝酸盐燃烧的无定形产物进行热处理，有望获得纯六方改性的HoFeO _{3 。}
