| Vibrating Sample Magnetometer (VSM for short)is a made-up instrument based on the principle of electromagnetic induction, it could be regarded as a magnetic dipole whose magnetic moment was m when the adopted sample with lesser size was magnetized in the magnetic field. Making a sample shaked in tittle swing at a certain way, and using a set of director coil in series reverse connection one another induced the change of this magnetic dipole around the sample, then we could find that the induced electromotive force of director coil had direct ratio straightly with the sample's intensity of induced magnetization. VSM is often used in measure of magnetic moment, Curie temperature and the magnetic hysteresis cycle. However, it could not find full information of magnetic material just having the measure the magnetic moment, Curie temperature and the magnetic hysteresis cycle for the magnetic material. Kainotype R3(Fe,M)29(R= rare-earth(RE);M= transition element) is freshly finding RE-Iron metal compound with broad research worth. Now, the work on substitute with magnetism and non-magnetism element to RE and transition element in experiment was still not put up about 3:29 type RE-Iron metal compound, and the research was not developed on sides of commuting reciprocity, magnetism-crystal anisotropy, spin tropism renewedly etc. in theory. For the sake of finding deferent influence about replacing RE and transition metal Co to Nd3(Fe,Ti)29 compound's magnetism-crystal anisotropy, we improved the VSM, worked out experimental device for studying magnetism-crystal anisotropy, so we could determine magnetism-crystal anisotropy well and truly...
