Revealing field-driven distorted conical spiral phase in a weakly anisotropic double helical antiferromagnet

Complex magnetic phase diagram driven by competing exchange interactions

The Kagome antiferromagnet YMn₆Sn₆ crystallizes in a hexagonal structure (P6/mmm space group) with lattice constants of a = b = 0.552 nm and c = 0.899 nm, as…
