the dipolar interaction of the particles. The field dependence of magnetization was fitted with revised Langevin equation.The magnetization of the weak ferromagnetic(WF) canted spins contributes to the linear portion in the high field region;the surface uncompensated spins and the parasitic ferromagnetic moments due to the canted spins both contribute to the particle moments and the superparamagnetic......

of the interfacial uncompensated spins within the FeMn bottom interfacial monolayers,whereas a relaxation of the pinning strength of the FeMn interfacial spins along the out-of-plane direction occurs......
an external field of 100 Oe and M-T curves exhibited two symmetrical branches for field cooling(FC) and zero field cooling(ZFC) modes.This behavior indicated the coexistence of canted antiferromagnetic... complex magnetization might be attributed to the interaction between paramagnetic Ho3+ moments and canted Cr3+ moments.关键词:......

of cobalt content; experimental results pointed to the existence of disordered spins interactions, which were more evident with the decrease of cobalt content and the existence of ferromagnetic coupling among spins of the samples. These results showed the feasibility of producing a family of compounds with the desired properties, manipulating composition and therefore the microstructure.关键......
