Sažetak
Superconductivity in 2H-TaSe2, a two-dimensional dichalcogenides, were studied by resistivity and susceptibility measurements. In-plane electrical resistivity starts to decrease at 500 mK and becomes essentially zero at 200 mK indicating the superconducting transition. The transition width is broad probably due to lattice imperfections or mixing with other crystalline phases than the 2H type. More precise estimation of transition temperature from the susceptibility data gives Tc _ 150 mK, and appearance of inflexion point in susceptibility is an evidence of possible existing two crystalline phases in this material.
