Extended Data Fig. 8: Spontaneous MCD in samples with different twist angles.
From: Thermodynamic evidence of fractional Chern insulator in moiré MoTe2
Integrated MCD as a function of filling factor and electric field in 3 different samples with twist angles of 2.1 degrees (a), 2.7 degrees (b) and 4.6 degrees (c). All data were acquired at T = 1.6 K and B = 20 mT. The incident light was kept below 20 nW on the sample. Ferromagnetism is observed over a wide range of twist angles.
