N2 - The electrical resistivity and magnetization M(H) of single crystal CeRhAs, which is the so-called Kondo insulator, have been measured in magnetic field up to 55 T. At 1.3 K, the slopes of M(H b) and M(H∥c) decrease at around 16 and 13 T, respectively, while M(H∥a) increases monotonously. The longitudinal magnetoresistances along the b- and c-axes show characteristic structures partly associated with the anomaly of M(H), while it along the a-axis shows only a broad maximum. The transverse magnetoresistances for I/:b follow Hγ (γ = 1.5-1.7). These observations suggest the existence of a narrow and anisotropic structure within the wide pseudogap.
