摘要：
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 T-C = 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)mu(B) and 1.7(4)mu(B), respectively, at T = 2K.
