2D ferromagnetic chromium tellurides exhibit intriguing spin configurations and high-temperature intrinsic ferromagnetism, providing unprecedented opportunities to explore the fundamental physics build spintronic devices. Here, a generic van der Waals epitaxial approach is developed synthesize ternary tellurium compounds with thicknesses down mono-, bi-, tri-, few-unit cells (UC). The Mn0.14 Cr0.86 Te evolves from behavior in bi-UC, tri-UC, few-UC temperature-induced ferrimagnetic as thickness increases, resulting sign reversal of anomalous Hall resistance. Temperature- thickness-tunable labyrinthine-domain behaviors are derived dipolar interactions Fe0.26 Cr0.74 Co0.40 Cr0.60 Te. Furthermore, dipolar-interaction-induced stripe domain field-induced wall (DW) motion velocity studied, multibit data storage realized through an abundant DW state. magnetic can function neuromorphic computing tasks, pattern recognition accuracy reach up 97.93%, which similar ideal software-based training (98.28%). Room-temperature significantly promote exploration processing, sensing, based on systems.
