Abstract: The structure and magnetic properties of CdGd2(WO2)4 single crystal were studied by X-ray diffraction, magnetic measurement and electron spin resonance (ESR) experiments. The results showed that the crystal structure is tetragonal with lattice parameters a=b=0.5204 nm and c=1.136 0 nm. σ-T and ESR experiments showed that the crystal is paramagnetic and anisotropic. The magnetic properties of the crystal reflected its structure characteristics well. Landé factor g2 tensor was calculated, and found to be consistent with the result obtained by theoretical calculation.

Key words: ESR, paramagnetism, anisotropy, CdGd2(WO2)4 single crystal, magnetism
