- Abstract
The electrical and magnetic properties of thermally evaporated In0.95Co0.05Sb thin film are studied in detail. The X-ray diffraction analysis indicated a single-phase polycrystalline film structure with an average grain size of ~ 35 nm. DC resistivity directed that at low temperatures (< 230 K), the film's resistivity is magnetic field dependent. A systematic investigation of temperature and magnetic field-dependent transport properties is undertaken. This field-dependent low-temperature behavior of the film is explained based on electron–electron, electron–phonon, electron-magnon, and Kondo-like spin-dependent scattering theories. The low-temperature data are estimated for the density of states using variable range hopping theory, whereas the Arrhenius plot is explored using the high-temperature resistivity behavior of the film. The surface morphological study indicated a uniform particle distribution. The weak magnetic signals are observed through magnetic force microscopy. The temperature-dependent magnetization curve shows the film's superparamagnetism nature applicable to the spintronic devices.
