Note on the Magnetic Anisotropy of the Cobalt Ammonium Tutton Salt Co(NH4)2(SO4)2·6H2O

Magnetic anisotropy of cobalt ammonium Tutton salt in the temperature region from about 10°K to 300°K is studied, where we used the wave functions obtained by Abragam and Pryce. The temperature dependence of the effective Bohr magneton is also studied. The agreements of the present theoretical results with the experimental ones are excellent.
