%X The magnetic structures of the Eu2+ and Cr2+ moments in the nonsuperconducting parent compound EuCr2As2 have been determined by using neutron diffraction. While the Eu2+ moments order ferromagnetically with moments along the c direction at TC=21.0(1) K, the ordering temperature of the Cr2+ moments is found to be at very high temperature of 680(40) K by using magnetization measurements. The Cr2+ moments order in a G-type antiferromagnetic structure with moments along the c direction. According to this magnetic structure, the nearest-neighbor Cr2+ moments are antiferromagnetically aligned in the a−b plane as well as in the c direction. The ordered magnetic moment of the Eu2+ and Cr2+ amounts to 6.2(5)μB and 1.7(4)μB, respectively, at T=2 K.
