The intensity of magnetic field is indicated by the energy separation between the Zeeman sublevels in ground state of rubidium atom. The optical-radio frequency double resonance technique is used to observe the energy separation. The frequency of the applied rf-field which indicates the intensity of the magnetic field is locked by Automatic Frequency Control (A.F.C.) system. The A.F.C. system is consists of the Lock-in-Amp and Voltage Control Oscillator (V.C.O.). The precision of the apparatus was 10γ. The daily change of magnetic field of earth was observed. The other types of rubidium magnetometer are discussed also in this paper.}, pages = {107--115}, title = {ルビジウム原子の光ポンピングによる磁力計}, volume = {11}, year = {1978} }
