Abstract

Abstract: High quality Sr4 Ru3 O10 nanoflakes are obtained by the scotch tape-based micro-mechanical exfoliation method. The metamagnetic transition temperature T m f l a k e is found to decrease in line with the decrease of thickness, while the ferromagnetic (FM) phase, the ordinary, and anomalous Hall effects (OHE and AHE) are independent on the thickness of the flake. Analysis of the data demonstrates that the AHE reflects the FM nature of Sr4 Ru3 O10, and the decrease of thickness favors the Ru moments aligned in the ab -plane, which induces a decrease of the metamagnetic transition temperature compared with the bulk.
