We study a quantum liquid which consists of Bose-particles each carrying a magnetic moment. The thermodynamic and structure functions of the system are calculated in the random phase approximation using functional integration techniques. The obtained expressions are valid in the low-temperature regime and recover the known results of the classical magnetic liquids theory as a limiting case. In particular, the influence of the magnetic degrees of freedom as well as of the external magnetic field on the phenomenon of Bose-condensation is studied.
