,so that no giant magnetocaloric effect was found.The samples made of purified Gd exhibit first order phase transformation,and the -ΔSm is basically consistent with the published data of Ames laboratory,USA.This work proves that Gd-Si-Ge alloys made of domestic Gd can be utilized in magnetic refrigerators. Key words:metal materials; giant magnetocaloric effect; Gd-Si-Ge alloys; Gd; impurity; rare......
powder calcined at 1 100 ℃. The effects of ZB on the microstructure and dielectric properties of CCTO ceramics were investigated. And the dielectric mechanism with giant dielectric constant was also...-doped CCTO ceramics indicate that CCTO ceramics consist of semiconducting grain boundaries and insulating grains, which results in the giant dielectric constant of CCTO ceramics. Key words......

spin valve giant magnetoresistance (SV-GMR) in nanoscale were investigated experimentally and theoretically by nanosized magnetic simulation methods. Based on the Landau-Lifshitz-Gilbert equation, a model with a special gridding was proposed to calculate the giant magnetoresistance ratio (MR) and investigate the magnetization reversal mode. The relationship between MR and the external magnetic......
