A brief report on the experimental evidence and theoretical explanation of substantial effects of a permanent magnetic field (PMF) of B=0–2 T on 1/f noise in HgCdTe n[sup +]-p high performance planar photodiodes (HPPD) is presented. It is shown that the PMF suppresses 1/f noise in the HPPD at lower frequencies f[sup L]f[sub 0]. These PMF effects follow from the earlier proposed nanoscopic stochastic theory of 1/f noise in solids. The proposed theoretical model is in good agreement with observations. © 2001 American Institute of Physics.
