Abstract

Theoretical and experimental studies of the magnetic field distribution in the space between two cylindrical permanent magnets with through holes in the center have been carried out. In the middle of a space measuring 2 × 2 × 2 mm³ near the symmetry axis, a magnetic field with an inhomogeneity of no more than 3% was found and one in the region of 1 × 1 × 1 mm³ with less than 1% was found. Based on the calculated and experimental results, a setup for determining the Verdet constant (V) using neodymium permanent magnets was developed and manufactured. The magneto-optical constants for samples of optical ceramics from Tb₂O₃ and Tb₃Ga₅O₁₂ at wavelengths of 0.628 and 1.06 µm are determined.

两块永磁体之间间隙中的磁场分布：计算和实验数据及其应用

我们对两个中心有通孔的圆柱形永磁体之间空间的磁场分布进行了理论和实验研究。在靠近对称轴的 2 × 2 × 2 mm3 空间中间，发现磁场的不均匀性不超过 3%，而在 1 × 1 × 1 mm3 区域，发现磁场的不均匀性小于 1%。根据计算和实验结果，开发并制造了一套利用钕永久磁铁测定 Verdet 常数 (V) 的装置。测定了波长为 0.628 和 1.06 微米的 Tb2O3 和 Tb3Ga5O12 光学陶瓷样品的磁光常数。
