Abstract: Thin films of Dirac semimetal Cd$_{3}$As$_{2}$ about 100 nm thick made of single crystals of cadmium arsenide, prepared by direct fusion of the elements by vacuum–ampoule method, by vacuum–thermal sputtering/depostion have been studied. Temperature and magnetic field dependences of electrical resistance have been measured, which indicate the presence of a superconducting transition at a temperature from 0.2 to 0.6 K.

Keywords: Dirac semimetal, superconductivity, thin film.
