Enhanced $d$-$p$ hybridization intertwined with anomalous ground state formation in van der Waals-coupled magnetic metal Fe$_5$GeTe$_2$

Autor: Yamagami, K., Fujisawa, Y., Pardo-Almanza, M., Smith, B. R. M., Sumida, K., Takeda, Y., Okada, Y.

Fe$_5$GeTe$_2$ is a van der Waals (vdW)-coupled unconventional ferromagnetic metal with a high Curie temperature ($T_C$) exceeding 300 K. The formation of an anomalous ground state significantly below $T_C$ has received considerable attention, result

We report on observations of very high-energy gamma rays from the shell-type supernova remnant Cassiopeia A with the VERITAS stereoscopic array of four imaging atmospheric Cherenkov telescopes in Arizona. The total exposure time for these observation
