Unique Helical Magnetic Order and Field-Induced Phase in Trillium Lattice Antiferromagnet EuPtSi

Koji Kaneko, Matthias D. Frontzek, Masaaki Matsuda +8

Magnetic transition phenomena in cubic chiral antiferromagnet EuPtSi with $T_{\mathrm{N}}$=4.0~K were investigated by means of single crystal neutron diffraction. At 0.3~K in the ground…
