a Crystal structure of YMn6Sn6. b c-axis view of the structure showing Mn atoms arranged in a kagome-net in the ab-plane. c Schematic temperature (T) and magnetic field (H) phase diagram of YMn6Sn6 labeled for the various magnetic phases for field applied in the ab-plane including the distorted spiral (DS), transverse conical spiral (TCS), fan-like (FL), and forced ferromagnetic (FF) phases. Small pockets labeled as I and CAF represent phase I and the canted antiferromagnetic phase, respectively. d Plot of the wavevector (L = kz) of the magnetic Bragg peaks observed in neutron diffraction experiments at 10 K (red lines) and illustrations of the magnetic structures for DS, TCS, FL, and FF phases. Magnetic fields at which transitions from DS to TCS, TCS to FL, and FL to FF are indicated by H1, H2, and H3, respectively. Arrows represent the direction of spins in each Mn-layer. The labels c and x represent c-axis and the direction of magnetic field in the ab-plane, respectively.
