The influence of temperature on the magnetic hysteresis and coercivity of Co magnetic nanowires was investigated by Monte Carlo method. Monte Carlo simulation results of hysteresis loop indicated that both its tendency and the coercivity were consistent with experimental results within a given error. The coercivity was calculated with the temperature and the angle between nanowires and magnetic field applied, varying the temperature from 50K to 300K for Co nanowires with a diameter of 30nm. The coercivity decreased monotonically at all values of angle with the increase of temperature T, following the parabolic curve of T-γ. The power exponent γ, determined corresponding to angle between nanowires and magnetic field, was 0.03~0.06 and was consistent with the previous experimental results.
