Abstract
Magnetization and magnetoresistance have been measured in insulating antiferromagnetic La2Cu0.97Li0.03O4 over a wide range of temperatures, magnetic fields, and field orientations. The magnetoresistance step associated with a weak ferromagnetic transition exhibits a striking nonmonotonic temperature dependence, consistent with the presence of Skyrmions.
摘要
磁化强度和磁电阻在宽温度范围、磁场和磁场方向下在绝缘反铁磁 La2Cu0.97Li0.03O4 中进行了测量。与弱铁磁转变相关的磁电阻阶跃表现出显著的非单调温度依赖性，与斯格明子的存在一致。
