论文摘要
我们使用实验测量的磁化，特定的热量，磁铁，电阻，热扩散率和热导率参数，通过直接和间接测量介绍了PR0.7SR0.2CA0.1MNO3中磁联性效应（MCE）的比较结果。我们已经证明，每个参数的变化响应于材料的铁磁 - 磁磁相变温度附近的磁场与磁熵的变化相关。这些发现使我们能够相互关联这些参数，并提供了一种访问磁平衡材料有用性的替代，有效的方法。
We present the results of a comparative analysis of the magnetocaloric effect (MCE) in Pr0.7Sr0.2Ca0.1MnO3, through direct and indirect measurements, using experimentally measured magnetization, specific heat, magnetostriction, resistivity, thermal diffusivity and thermal conductivity parameters. We have demonstrated that the change in each parameter in response to a magnetic field near the ferromagnetic-paramagnetic phase transition temperature of the material correlates with the change in magnetic entropy. These findings allow us to interrelate these parameters and provide an alternative, effective approach for accessing the usefulness of magnetocaloric materials.
