The electrical resistivity p and the thermoelectric power S of Mn3–xCoxGaC(x≤0.12) are studied to investigate the mechanism of the magnetic order-order transition. The ρ-T curves for samples with 0<x≤0.06 show the appearence of an intermediate magnetic phase. The experimental results suggest that the magnetic phase transitions of Mn3−xCoxGaC should be discussed in terms of itinerant electron magnetism.

Topological Phase Transitions

Abstract In this work, we investigate the topological phase transitions and corresponding transport properties in zigzag stanene nanoribbon with different magnetism. The results show that the off-resonant circularly polarized (ORCP) light may induce anisotropic chiral edge state with a magnetic phase transition from antiferromagnetic state to nonmagnetic state. In combination with the ORCP light and electric field, the 100% spin-polarized edge state can be induced with some magnetic orders. The finite-size effect is also an important factor for the magnetic phase transitions, which in turn induces topological phase transitions from the band insulator to topological phases. By constructing the topological-insulator junctions with some topological edge states, we further study the Fabry-Perot resonant, where multiple reflection edge states cause strong current loops. By modulating the ORCP and electric field, the system can also be regarded as a switcher, to control the charge current or spin polarized current. These findings pave a way for designing topological device with magnetic edges in the future nano spintronics.
