Abstract: Temperature and field dependences of the magnetic moment in the temperature range 4 K < T < 300 K and electron spin resonance linewidths and the g-factor in the temperature range 80 K < T < 300 K for the Bi24(CoBi)O40 compound synthesized by the solid-state reaction are analyzed. The magnetic susceptibility of Bi24(CoBi)O40 within the range 4 K < T < 300 K is described well by the Curie-Weiss law with the negative paramagnetic Curie temperature θ = −12.3 K and the effective magnetic moment µ = 5.08µB. The g-factor and the ESR linewidth grow with temperature.
