微振样品磁强计可用于研究在外磁场下物质磁性的各种表现。文中对仪器应用的原理,机械构造,探测线圈的设计,电子线路及工作特性做了叙述。对本方法的优缺点及适用范围也做了简要评论。仪器有成套性,除测量磁矩系统外,尚附有霍尔测量磁场系统。测量磁矩范围是:10~(-4)～10~2电磁单位磁矩,分辨率不低于2×10~(-5)电磁单位磁矩,在中等灵敏度下相对精度不低于1%。霍尔测场误差在中等磁场下不大于1%。
Micro-vibration sample magnetometer can be used to study the magnetic properties of the material under various external magnetic field performance. The article describes the principle of the instrument, the mechanical structure, the design of the detecting coil, the electronic circuit and the working characteristics. The advantages and disadvantages of this method and the scope of application also made a brief comment. Instrument is complete, in addition to measuring the magnetic moment system, is still attached Hall magnetic field measurement system. Measuring magnetic moment range: 10 ~ (-4) ~ 10 ~ 2 Magnetic moment of electromagnetic unit, the resolution is not less than 2 × 10 ~ (-5) Magnetic moment of magnetic unit, the relative accuracy of medium sensitivity is not less than 1% . Hall test error less than 1% in the medium magnetic field.
