Magnetic properties of oxides and silicon single crystals

The data related to the article “Magnetic properties of oxides and silicon single crystals” published in the journal Chinese Physics B. The magnetic properties of single crystals Si, SrTiO3, LaAlO3, MgO, and (La,Sr)(Al,Ta)O3 were investigated systematically. These crystals were also often used as substrates for the growth of thin film materials, including magnetic thin film materials. Three origins of the magnetizations of these crystals, namely, an intrinsic diamagnetic, a paramagnetic, and a ferromagnetic contribution, have been observed. The experimental results were quantitatively analyzed and the corresponding theoretical analysis methods were developed, which led to a number of parameters of the intrinsic physical properties of these crystalline materials. In particular, the experimental parameters of variation of diamagnetic susceptibility with temperature of several oxides SrTiO3, LaAlO3, MgO, and (La,Sr)(Al,Ta)O3 single crystals were obtained for the first time. The data contain an Excel file, which gives diamagnetic susceptibility at room temperature (χdia), variation of diamagnetic susceptibility with temperature (dχdia/dT), saturation magnetization at room temperature (MS,ferro), paramagnetic magnetization at temperature 2 K and field 4.85 T (Mpara (4.85 T, 2 K)) and impurity concentration (Imp. Con.) of the single crystals.

与发表在《中国物理B》期刊上的文章《氧化物和硅单晶的磁性质》相关的数据集。本研究系统性地探讨了单晶Si、SrTiO3、LaAlO3、MgO以及(La,Sr)(Al,Ta)O3的磁性质。这些晶体常被用作薄膜材料，包括磁性薄膜材料的生长基底。对这些晶体的磁化起源进行了三种类型的观察，即内禀抗磁性、顺磁性和铁磁性贡献。实验结果得到了定量分析，并发展了相应的理论分析方法，从而得出了这些晶体材料的内在物理性质的一系列参数。特别是，首次获得了几种氧化物SrTiO3、LaAlO3、MgO和(La,Sr)(Al,Ta)O3单晶的电阻率随温度变化实验参数。数据集包含一个Excel文件，其中提供了室温下的抗磁性电阻率（χdia）、抗磁性电阻率随温度的变化率（dχdia/dT）、室温下的饱和磁化率（MS,ferro）、2K温度和4.85T磁场下的顺磁性磁化率（Mpara (4.85 T, 2 K)）以及单晶的杂质浓度（Imp. Con.）。
