摘要：

This study is devoted to the thermal and magnetic properties of the 2D Klein-Gordon oscillator in a cosmic string space-time. These properties are determined by the partition function based on the Poisson approximation. We provide analytic expressions for the partition function and analyze the entropy, specific heat, magnetization, and magnetic susceptibility of this system numerically. We focus on the effect of a cosmic string, the applied magnetic field, and the temperature on these properties. The results show a totally negative magnetization of our oscillator.
