Mn掺杂$SnO_{2}$薄膜的室温铁磁性
Room temperature ferromagnetism in transparent and conducting Mn-doped $SnO_{2}$ thin films
摘要：
在室温下，磁化强度随磁场的变化表现出滞后行为。根据磁化强度的温度依赖性，居里温度$(T_{C})$高于350 K。Mn掺杂的氧化锡薄膜在可见光区（400-800 nm）表现出低电阻率和高透光率。Mn掺杂的$SnO_{2}$薄膜中铁磁性、高可见光透明度和高电导率的共存有望成为自旋电子器件的理想特性。
英文摘要：
The magnetization as a function of magnetic field showed hysteretic behavior at room temperature. According to the temperature dependence of the magnetization, the Curie temperature $(T_{C})$ is higher than 350 K. Ferromagnetic Mn-doped tin oxide thin films exhibited low electrical resistivity and high optical transmittance in the visible region (400-800 nm). The coexistence of ferromagnetism, high visible transparency and high electrical conductivity in the Mn-doped $SnO_{2}$ films is expected to be a desirable trait for spintronics devices.
