[en] The quantum mechanics of charged, massive, spin-one bosons in the presence of a homogeneous magnetic field is studied using a six-component wave function formalism. The energy eigenvalues are compared to those previously obtained via other formalisms, the equations of motion of certain operators are given, and the positive and negative energy eigensolutions are obtained by the use of a ladder operator method. The six-component current for the case of general external electromagnetic fields is also displayed, and finally the employment of the eigensolutions and current in a study of a spin-one boson-anti boson plasma is discussed. 22 refs
