摘要

We study the spin reorientation in Fe3Sn2 by examining the anisotropic magnetoresistivity in detail, exploiting the dependence of the resistivity on the direction between magnetization and applied current. We determine the distribution of the magnetic domains as a function of temperature between 360 K and 2 K and find the reorientation transition to peak at 120 K. We discover that both out-of-plane and in-plane phases coexist at temperatures around the spin reorientation, indicative of a first-order phase transition. Although the volume of the magnetic domains in the different phases sharply changes at the spin reorientation transition, no appreciable changes in the electronic structure for a specific magnetization is detected by anisotropic magnetoresistivity at the spin reorientation. In contrast, we observe an electronic transition around 40 K, hitherto unreported, and reflected in both the zero-field resistivity and anisotropic resistivity.
