Unusual magnetic and transport properties in HoMn6Sn6 kagome magnet
Description
With intricate lattice structures, kagome materials are an excellent platform to study various fascinating
topological quantum states. In particular, kagome materials, revealing large responses to external stimuli such as
pressure or magnetic field, are subject to special investigation. Here we study the kagome-net HoMn6Sn6 magnet
that undergoes paramagnetic to ferrimagnetic transition (below 376 K) and reveals spin-reorientation transition
below 200 K. In this compound, we observe the topological Hall effect and substantial contribution of anomalous
Hall effect above 100 K. We unveil the pressure effects on magnetic ordering at a low magnetic field from
the pressure tunable magnetization measurement. By utilizing high-resolution angle-resolved photoemission
spectroscopy, Dirac-like dispersion at the high-symmetry point K is revealed in the vicinity of the Fermi level,
which is well supported by the first-principles calculations. Our investigation will pave the way to understanding
the magnetotransport and electronic properties of various rare-earth-based kagome magnets.
