Chemisorption of hydrogen on cobalt

The change in saturation magnetization of small particles of cobalt upon adsorption of hydrogen has been measured. It has been found that the average hydrogen atom chemisorbed decreases the magnetization by about 0.5 Bohr magnetons. This result, together with previous results on the effect of hydrog...
