Magnetic Properties of Nd12Co6Pb Compound () Abstract:The magnetic and magnetocaloric properties for the Nd12Co6Pb compound were investigated. The Curie temperature TC of the magnetic transition of Nd12Co6Pb compound is 194 K. The experimentally determined magnetic effective paramagnetic moment is μeff=12.36 μB per formula unit (3.49 μB per Nd atom). The maximum magnetic entropy change......

Influence of Non-Magnetic Substitutional Atoms on Spontaneous Moment and Curie Temperature of Ce2Co17 Compounds 刘正义1,胡社军2 (1.Mechano-Electronic Engineering Department, South China University of Technology, Guangzhou 510641, China;2.Faculty of Materials and Energy, Guangdong University of Technology, Guangzhou 510643, China) Abstract:The structure and magnetic properties of Ce2Co17-xMx(M=Ga,Al......
and the magnetic property of the SmCo5 compound.According to the calculated results, the magnetic moment per Sm is 1.29μB in the SmCo5 compound, which agrees with that of experiments.The analyzed result reveals that some negative exchange couplings occurring at six energy levels induce the distinct decrease of Curie temperature and the magnetic moment per Co.The valence electron numbers of 2.48, which......
of composites. There exist some magnetic resonance for the composite containing high microwire concentration. The natural ferromagnetic resonance(NFMR) comes from the precession of the magnetic moment..., there is magnetic component in the radial direction of most microwires of A-type composite. The moment of the microwires being most axially magnetized is excited by the microwave, resulting in the precession......

to investigate the magnetic properties, electronic structure and bonding mechanism of FeF2. By calculating the lattice parameters and magnetic moment as a function of effective interaction parameter (Ueff), it is found that the optimum value of Ueff is equal to 4 eV, the magnetic moment is 3.752 μB and the value of c/a is 0.704, which are in good agreement with the experiment results. Simultaneously......
