Hydrostatic pressure to trigger and assist magnetic transitions: baromagnetic refrigeration
摘要：
利用压热效应制造固体制冷机的可能性是应用物理领域的一个热门课题。在这项工作中，我们提出的实验数据的影响，外部压力的磁性能的锰氧化物与相分离。使用Jahn Teller效应与电荷有序的存在，我们能够遵循由压力引起的铁磁态的转变。我们还证明，外部压力可以帮助铁磁状态，减少产生磁转变所需的磁场。
英文摘要：
The possible application of the barocaloric effect to produce solid state refrigerators is a topic of interest in the field of applied physics. In this work, we present experimental data about the influence of external pressure on the magnetic properties of a manganite with phase separation. Using the Jahn Teller effect associated with the presence of the charge ordering we were able to follow the transition to the ferromagnetic state induced by pressure. We also demonstrated that external pressure can assist the ferromagnetic state, decreasing the magnetic field necessary to generate the magnetic transition.
