These transitions were also manifested by the slope change of temperature-dependent resistivity, i. paramagnetic-incommensurate collinear antiferromagnetic transition at T. We show three magnetic multiple antiferromagnetic transitions phase transitions with transition temperatures at T M1 = 35 K (long-range antiferromagnetic transition), T M2 = 101 K (antiferromagnetic-type transition) and multiple antiferromagnetic transitions T M3 = 120 K (ferromagnetic-like transition). · Prof Tamura says, "Antiferromagnetic transitions have been observed in 1/1 approximants, but we observed multiple antiferromagnetic transitions it in a 2/1 approximant for the first time. Quantum phase transitions arise in many-body systems because of competing interactions that promote rivaling ground states. Using time-resolved far-infrared spectroscopy, we observe multiple routes for photoinduced phase transitions in V2O3.
