Summary: | We herein report on a fast and convenient soft-chemical synthesis approach
towards large 1T-CrTe2 van-der-Waals crystals. This compound is formed X-ray
diffraction pure, with a complete conversion within just over 2 h from
flux-grown LiCrTe2 crystals using diluted acids. Due to the availability of
high-quality single crystals, we have confirmed the crystal structure for the
first time by single-crystal X-ray diffraction experiments. For the acid
deintercalated 1T-CrTe2 crystals, we find long-range ferromagnetic order with a
Curie temperature of $T_{\rm C}$ = 318 K. We further revealed the magnetic
structure of 1T-CrTe2 using low-temperature neutron powder diffraction
experiments and determine the magnetic Hamiltonian using density functional
theory. X-ray diffraction experiments of post-annealed crystals suggest a
thermal stability of 1T-CrTe2 up to at least 100 {\deg}C. Our findings expand
the synthesis methods for 1T-CrTe2 crystals, which hold promise for integrated
room-temperature spintronics applications. |
