As a kagome Weyl semimetal with a high Néel temperature, Mn3Ga has attracted interest due to its large anomalous Hall and topological transport properties. We performed angle-dependent magnetoresistance measurements on the Mn3Ga thin films and observed a distinct anomaly in the temperature evolution and angular dependence of the resistivity. The change in the angular profile indicates a...
Accessing milli-Kelvin temperatures is a prerequisite for quantum-matter research and applications in quantum technologies. Adiabatic demagnetization refrigeration (ADR) is a simple and sustainable alternative to 3He/4He dilution refrigeration. Geometrically frustrated triangular and kagome rare earth oxides feature important advantages compared to the traditionally utilized hydrated...
While correlated phenomena of flat bands have been extensively studied in twisted systems, the ordered states that emerge from interactions in the intrinsic flat bands of kagome lattice materials remain largely unexplored. The newly discovered kagome metal CsCr3Sb5 offers a unique and rich platform for this research, as its multi-orbital flat bands at the Fermi surface result in a complex...
