本文系统地介绍JDM—14型振动样品磁强计(VSM)的一种应用软件。通过本软件,可以自动求得规则样品的平均退磁因子,从而,把振动样品磁强计测量开路样品的磁参数自动转化为闭路样品(即物质)的磁特性参数。在已知样品质量和密度、或者样品体积的情况下,可以自动求出该物质的磁化强度、饱和磁化强度、磁化率、矫顽力、内凛矫顽力、剩磁以及磁化曲线、磁滞回线、退磁曲线和磁能积曲线等。
This article systematically introduces an application software for the JDM-14 vibrating sample magnetometer (VSM). Through this software, the average demagnetization factor of the regular sample can be automatically calculated, so that the magnetic parameters of the open-circuit sample measured by the vibrating sample magnetometer are automatically converted into the magnetic properties of the closed-circuit sample (ie, material). The magnetization, saturation magnetization, magnetic susceptibility, coercivity, coercive force, coercivity, remanence and magnetization curve of the material can be automatically determined in the case of known sample mass and density, or sample volume, hysteresis Back to the line, demagnetization curve and magnetic energy product curve.
