We have observed current-induced 1 f{hook} noise in thin copper crystals ("whiskers") ranging from 0.15 to 1.20 cm in length. We find that the noise power is proportional to the square of the applied d.c. voltage and has a power spectrum varying approximately as f{hook}-1 over the frequency range 0.5 Hz-2 kHz. The magnitude of the noise is 102-103 times larger than typical magnitudes reported for copper films of similar volume.
