Abstract

Some layered phyllosilicates are characterized by spontaneous scrolling due to size mismatch between sublayers. The doping of layers by transition metal ions allows nanoscrolls to acquire magnetic properties. The magnetic behavior of synthetic (Mg_{1 –} _xCo_x)₃Si₂O₅(OH)₄ (x = 0.2, 0.4, 0.6, 0.8, 1) phyllosilicates with the chrysotile structure before and after partial hydrogen-induced reduction is studied. The dominant ferromagnetic behavior has been revealed in all studied phyllosilicates. Ensembles of cobalt metal nanoparticles in a silicate matrix have demonstrated a collective magnetic response at room temperature with a narrow hysteresis loop and fast saturation.

(Mg1 - xCox)3Si2O5(OH)4 纳米卷及其纳米复合材料的磁性能

由于子层之间的尺寸不匹配，一些层状植硅体具有自发卷动的特征。过渡金属离子在层间的掺杂可使纳米卷轴获得磁性。本文研究了部分氢诱导还原前后具有温石棉结构的合成 (Mg1 - xCox)3Si2O5(OH)4 (x = 0.2, 0.4, 0.6, 0.8, 1) 层状硅酸盐的磁性行为。在所有研究的绿硅酸盐中都发现了主要的铁磁行为。硅酸盐基质中的钴金属纳米粒子集合体在室温下表现出了集体磁响应，具有窄磁滞回线和快速饱和的特点。
