The magnetic structure of TlCrTe2
چکیده انگلیسی
The magnetic structure of the antiferromagnetic layer compound TlCrTe2 has been determined by neutron powder diffraction. The magnetic moments on chromium are aligned along the c axis in the hexagonal cell and couple ferromagnetically within the sheets. Adjacent layers couple antiferromagnetically below the transition temperature of 145 K. This gives rise to a doubling of the c axis for describing the magnetic unit cell. The magnetic moment of the chromium atom is 3.39(4) μB at 10 K in line with localised 3d3 of Cr3+. Electronic structure calculations on TlCrTe2 of density-functional type (GGA) show a clear driving force for the ferromagnetic coupling in the layers and a lowering of the total energy upon magnetic ordering, the theoretical magnetic moment being in almost quantitative agreement with the experiment.
