2014年9月5日 · We measured the Raman spectra of ferromagnetic, nearly half-metallic, CoS 2 over a broad temperature range. All five Raman active modes Ag, Eg, Tg (1), Tg (2) and Tg (3) were observed. The magnetic ordering is indicated by a change of the temperature dependences of the frequency and the line width of Ag and Tg (2) modes at the Curie point.

2019年7月29日 · Here, CoS 2 /CoS heterojunction nanoparticles with uneven charge distribution, which are synthesized in situ on graphite felt by a one-step solvothermal process, can significantly boost...

2021年9月1日 · As expected, the Graphdiyne-CoS 2 heterojunction nanocomposites exhibit superior HER catalytic performance with low overpotential of 97 mV at 10 mA cm −2, and the Tafel slope of 56 mV dec −1. Furthermore, the heterojunction shows outstanding stability as well due to the protection of the Graphdiyne (GDY).

2014年2月24日 · We measured the Raman spectra of ferromagnetic nearly half metal CoS2 in a broad temperature range. All five Raman active modes Ag, Eg, Tg (1), Tg (2) and Tg (3) were observed. The magnetic ordering is indicated by a change of the temperature dependences of the frequency and the line width of Ag and T g (2) modes at the Curie point.

We measured the Raman spectra of ferromagnetic nearly half metal CoS2 in a broad temperature range. All five Raman active modes A g, E g, T g(1), T g(2) and T g(3) were observed. The magnetic ordering is indicated by a change of the temperature dependences of the frequency and the line width of A g and T g(2) modes at the Curie point. The ...
