Magnetic Properties of (Cr_1-<i>y</i>V_<i>y</i>)_1-δTe (δ=0.14)

Abstract

Thermomagnetic properties of a solid solution between Cr 1-δ Te (a metallic ferromagnetic compound) and V 1-δ Te (a Pauli paramagnetic one) are investigated. The Curie temperature decreases with increasing y , and disappears at a triple point ( y =0.79, T =45 K). An extra magnetic phase is found beyond the triple point, which has the characteristics of spin glass or mictomagnetic states. At the transition temperature from the extra phase to the paramagnetic one, the χ vs T curve shows a sharp cusp even in a high field (6.3 kOe), The Curie constant C M ( y ) and the Weiss one θ p ( y ) are determined by means of a high temperature extrapolation procedure. Obtained values of C M ( y ) indicate that the average magnetic moment per Cr atom is nearly constant over the whole range of y . A deviation of θ p ( y ) from the linear dependence on y is observed.
