Unusual behavior of anisotropic magnetoresistance (AMR) has been encountered in low-doped La0.78Ca0.22MnO3 single crystals. In contrast with previous studies of AMR in manganites, as the maximal effect was observed around TC, the AMR of La 0.78Ca0.22MnO3 single crystals (TC ≈ 189 K) increases monotonously with decreasing temperature, reaches a maximum around 140 K, and then decreases with further temperature decrease. Moreover, around the maximum, AMR increases almost linearly with magnetic fields and only at fields exceeding H ∼ 7 kOe does it start to saturate. The observed unusual enhancement of AMR may be ascribed to the changes in magnetic domain structure at temperatures below 150 K as observed previously by us using a magneto-optical imaging technique.
