)) where a series of electromagnetic coils were mounted and generated regularly pulses of a magnetic field with an average density of 5.0 T and a frequency of 0.05 Hz (2 magnetic pulses/min). The schematic... strains on grain boundaries, which resulted in disintegration of inter-granular links. Theoretically, if a ferromagnetic material was introduced to a magnetic field, its length and volume would be changed......
acquire the global magnetic field. A scientific scheme is developed to get the signal processing and temperature compensation for nondirective weak magnetic field. The software of sampling control system is given, which is complied using C language in Labwindows/CVI. Taking computer as main engine, the system can acquire the nondirective weak magnetic field automatically and continuously use......

it a new type of materials promising in magnetic recording field[1-4]. With the development of high recording density application such as video and audio tape, instrumentatic tapes and flexible disks... the saturation magnetization of inner core Fe3O4, the greater the demagnetization field[7]. Different saturation magnetization can be obtained by controlling the content of FeO in Fe3O4[17]. The effect of magnetic......

Magnetic Properties and Molecular Field Analysis of (Ce,Nd)2(Fe,Si,Mn)17 Compounds 王润1,周寿增1,蔡新兴2,梁琍琍2,高小玫2,张茂才1 (1.School of Materials Science and Engineering, University of Science & Technology... intermetallic compounds were measured and analyzed by molecular field theory (MFT). The relationship between TC and the intrasublattice coupling interactions was discussed. The two-sublattice MFT model can......
effect, which is intrinsic to all magnetic materials, is a consequence of magneto-thermal couplings between the magnetic entropy and the lattice entropy. When a magnetic field is applied... decreases. Otherwise, the magnetic moments return to their random directions, and the materials absorb heat and their magnetic entropy increases when the magnetic field is reduced isothermally. The MCE......
