The Studies of Ac Magnetic Susceptibility and Higher Harmonics in Cd0.88Cr1.96V0.31Se4 Semiconductor

Abstract

The complex ac dynamic magnetic susceptibility was used to study the magnetic state in the polycrystalline Cd0.88Cr1.96V0.31Se4 spinel. The temperature dependences of the zero field in-phase (real part) and out-of-phase (imaginary part) components of fundamental susceptibility showed the mictomagnetic behavior at low temperature and a weak Hopkinson-like effect close to the ordering temperature. These effects are also evidenced by the non-vanishing both the real and imaginary components of the 2nd and 3rd harmonics in the region of magnetic order.
