by adjusting slurry temperature and pH value was able to enhance its magnetism, producing the so-called the magnetized pyrite, which was further used as magnetic seeds in the flotation of pyrite ore...-magnetization were pulp pH of 11.81 and temperature of 65 °C. The magnetized pyrite was characteristic of the valence change of elemental iron, resulting in stronger magnetism of the magnetized pyrite than......
Fabrication and Magnetic Properties of Highly Oriented ZnO:Eu Films by Sol-Gel Process车平,孟健,任丽荣,郭林摘 要:<正>A series of Eu-doped ZnO films were prepared by a sol-gel method. Precursor and films were characterized by thermal analysis (TG-DTA), X-ray diffraction (XRD), scanning electron microscope (SEM), UV-vis spectra, as well as the magnetism......
the hydrogen absorption/desorption(AD) process, the magnetism of the HSA changed. Researchers studied these phenomena, wanting to dig the deeper relationship between them, and to find the theoretical......
Comparison of room-temperature multiferroics in Bi4Fe2TiO12 film and bulkJun Lu, Lijie Qiao, and Wuyang Chu Department of Materials Physics, School of Materials Science and Engineering, University of Science and Technology Beijing, Beijing 100083, China摘 要:It was reported that both dielectricity and magnetism at room temperature were appreciably......
Trans. Nonferrous Met. Soc. China 27(2017) 204-210 Enhancement of pentlandite surface magnetism and implications for its separation from serpentine via magnetic separation Zhi-tao YUAN1, Ji-wei LU1... University, Zhengzhou 450001, China Received 5 November 2015; accepted 23 November 2016 Abstract: The magnetism of pentlandite surface was enhanced through the selective precipitation of micro-fine......
microscope (SEM), UV-vis spectra, as well as the magnetism measurement. The wurtzite structure of obtained films presents an extreme high c-orientation character. The film susceptibility resembles a Curie......
and nanowires are of room-temperature ferromagnetic. The magnetism of the nanotubes is much higher than that of the nanowires for the surface-preferential Co distribution. Key words: Zn1-xCoxO; nanowires... concentration and related defects structures are beneficial to the ferromagnetic coupling between Co ions [17,18], leading to the higher ferromagnetism of nanotubes. Fig. 5 Magnetism-Magnetic field intensity......
