We have observed a room-temperature ferromagnetism in chalcopyrile (Zn1-xMnx)GeP2 semiconductors with Tc =312 K. At temperatures below 47 K, sample for x = 0.056 shows a transition to the antiferromagnetic state, so that ferromagnetism is well defined to be present between 47 K and 312 K. However, in a slightly p-type doped (Zn1-xMnx)GeP2, ferromagnetic state is most stable at low temperatures.
