Abstract
Electrical resistivity and magnetoresistivity measurements were performed on MnRhAs between 4.2 K and 300 K. The reveal an anisotropic behaviour and strong anomalies giving evidence for changes in the magnetic ordering. The anomalies are most pronounced in measurements along the hexagonal easy axis. The resistivity curve recorded in the ferromagnetic state (160
