Abstract
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+−p high performance planar photodiodes (HPPD) is presented. It is shown that the PMF suppresses 1/f noise in the HPPD at lower frequencies fL<f0≈5–7 s−1 and increases it at higher ones fH>f0. 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.
