The effects of magnetic field on terahertz radiation emitted from the rectangular mesa of intrinsic Josephson junctions (IJJ's) made of Bi2212 single crystals were studied up to 150 Oe. Strong suppression of the radiation power was observed when magnetic field was applied to the c-axis of the sample, while in the case of H//ab-plane, the radiation power showed a weak and broad peak in the weak field region (similar to 50 Oe), then it decreased and diminished around 150 Oe. These magnetic field effects are interpreted by the strong influence of magnetic field on the I-V curve, which set up the condition for the THz radiation. (C) 2010 Elsevier B.V. All rights reserved.
