The
discovery of atomically thin van der Waals magnets (e.g., CrI3 and Cr2Ge2Te6) has triggered a renaissance in the
study of two-dimensional (2D) magnetism. Most of the 2D magnetic compounds
discovered so far host only one single magnetic phase unless the system
is at a phase boundary. In this work, we report the near degeneracy
of magnetic phases in ultrathin chromium telluride (Cr2Te3) layers with strong perpendicular magnetic anisotropy
highly desired for stabilizing 2D magnetic order. Single-crystalline
Cr2Te3 nanoplates with a trigonal structure
(space group P3̅1c) were grown
by chemical vapor deposition. The bulk magnetization measurements
suggest a ferromagnetic (FM) order with an enhanced perpendicular
magnetic anisotropy, as evidenced by a coercive field as large as
∼14 kOe when the field is applied perpendicular to the basal
plane of the thin nanoplates. Magneto-optical Kerr effect studies
confirm the intrinsic ferromagnetism and characterize the magnetic
ordering temperature of individual nanoplates. First-principles density
functional theory calculations suggest the near degeneracy of magnetic
orderings with a continuously varying canting from the c-axis FM due to their comparable energy scales, explaining the zero-field
kink observed in the magnetic hysteresis loops. Our work highlights
Cr2Te3 as a promising 2D Ising system to study
magnetic phase coexistence and switches for ultracompact information
storage and processing.
