负温度系数(NTC)热敏电阻的主要特点是温度灵敏度高、响应快、性能稳定,还具有体积小、结构简单的优点,因此被广泛用于测温、控温、温度补偿、抑制浪涌电流等设备中。YCrO3钙钛矿材料由于其磁电性质,已被广泛用于高温电极、热电、磁电材料等领域。其中,正交晶系钙钛矿结构的YCr1–xMnxO3(0≤x≤0.5)材料具有优异的电性能,被认为是潜在的NTC热敏电阻材料。然而,关于该体系材料的导电机理、离子相互作用机制等问题还没有完全解决,相关报道较少。中国科学院新疆理化技术研究所研究员常爱民带领其团队通过研究YCr1–xMnxO3(0≤x≤0.5)电性能,发现了材料电阻率随
Negative temperature coefficient (NTC) thermistor is characterized by high temperature sensitivity, fast response, stable performance, small size, simple structure, it is widely used in temperature measurement, temperature control, temperature compensation, surge suppression Current and other equipment. YCrO3 perovskite material has been widely used in the fields of high temperature electrode, thermoelectricity, magnetoelectric material due to its magnetoelectric properties. Among them, the YCr1-xMnxO3 (0≤x≤0.5) material of orthorhombic perovskite structure has excellent electrical properties and is considered as a potential NTC thermistor material. However, there are few reports on the conductive mechanism, ionic interaction mechanism and other issues of the system materials. Chang Aimin, a researcher at the Xinjiang Institute of Physics and Chemistry, Chinese Academy of Sciences, led his team to study the electrical properties of YCr1-xMnxO3 (0≤x≤0.5) and found that the material resistivity
