Abstract
- In this Letter, we studied the electrical transport, magnetic property, magnetoresistance and anomalous Hall properties of La-, Sm-, Ho-, and Dy-doped quasi-two dimensional K<subscript>0.58</subscript>RhO<subscript>2</subscript> single crystals. At low temperature (<10K), a significant magnetoresistance (36%) can be observed in these samples. Accordingly, the "glassy ferromagnetism" is revealed by temperature-dependent magnetization in these samples. The significant magnetoresistance is related to the granular ferromagnetism. The unconventional anomalous Hall effect is also observed in magnetic atoms doped samples. Our finding shields more light on the magnetic, magnetoresistance, and anomalous Hall properties of quasi-two-dimensional material systems doped with magnetic ions. [ABSTRACT FROM AUTHOR]
