18. 6 are increased, the stoichiometric ratio K/Fe tends to increase and the ratio Co/Fe tends to decrease.
19. Elemental analysis of the two compounds [(a) and (b)] obtained under the same preparation conditions (18) were as follows: (a) K, 1.74%; Co, 18.50%; Fe, 12.06%; C, 16.97%; N, 18.36%, H, 3 15%; and Cl, 0.3%.
20. 2O: K, 1.83%, Co, 19.34%; Fe, 13.09%; C, 16.89%; N, 19.70%; H, 3.27%; and Cl, 0%.
21. Typical experimental conditions a powder sample (200 to 300 μg) supported on a commercial transparent adhesive tape was placed on the edge of an optical fiber Light was shone onto the sample for 5 or 10 min The magnetization value was then measured after the light was turned off and the temperature reached a steady state. This cycle - illumination and measurement - was repeated.
22. The optical absorption spectrum showed that the absorbance at around 550 nm decreased and the peak at around 400 nm increased due to red light irradiation.
