摘要:

我们提出了一个实验装置开发,以执行光学光谱实验(拉曼散射和光致发光测量)与微米的空间分辨率,在低温,高磁场和高压的极端环境。据我们所知,这种独特的实验装置使我们能够通过独立调整这三个热力学参数来深入探索凝聚态系统的相图,同时监测低能激发(电子,声子或磁激发),以空间映射拉曼散射响应或研究低维物体。我们将这种技术应用到大块FePS3,层状反铁磁体与尼尔温度T = 120 K。

英文摘要:

We present an experimental set-up developed to perform optical spectroscopy experiments (Raman scattering and photoluminescence measurements) with a micrometer spatial resolution, in an extreme environment of low temperature, high magnetic field and high pressure. This unique experimental setup, to the best of our knowledge, allows us to explore deeply the phase diagram of condensed matter systems by tuning independently these three thermodynamic parameters, while monitoring the low-energy excitations (electronic, phononic or magnetic excitations), to spatially map the Raman scattering response or to investigate objects with low dimensions. We apply this technique to bulk FePS3, a layered antiferromagnet with a Neel temperature of T = 120 K.
