Magnetic properties of DyCo10V2

The easy magnetization direction of DyCo10V2 is parallel to the c axis at room temperature. The magnetization hysteresis loops of magnetically aligned samples were measured from 5 to 300 K with fields applied parallel and perpendicular to the alignment direction. For samples field-cooled to below the compensation temperatures, shifts of the loop centers into the range of negative magnetizations were observed. These features and the occurrence of negative remanences are explained in terms of the magnetization reversal when passing the compensation temperature upon cooling. From measurements of the temperature dependence of the magnetization, it was derived that a spin-reorientation transition takes place at about TSR=41 K.
