The Hall coefficient (R) of Hg^Mn^Te crystals has been found to behave anomalously at temperatures in the range Τ ~ 1.2-2 K: As the temperature is lowered, the Hall coefficient decreases and changes sign. The value of R depends on the magnetization of the sample. The observed features are attributable to the spontaneous Hall effect.
