Özet

The magnetic properties of Dy(Mn1-xCox)Sn-6 Were studied by field-cooled and zero-field-cooled magnetization measurements in the temperature range 5K less than or equal to T less than or equal to 600 K in low external fields and by magnetic field-dependent magnetization measurements in fields up to 50 kOe. The temperature variation of the ferrimagnetic spin configuration of the compound with x = 0, determined from earlier neutron diffraction experiments, was taken as the basis for the interpretation of the present data. We find that the overall magnetization at all temperatures and the ferrimagnetic Curie temperatures decrease with increasing Co content. Furthermore, the addition of Co leads to an initial increase in the coercivity at low temperatures up to x = 0.11, after which it decreases. (C) 2004 Published by Elsevier B.V.
