Pseudogap evidenced by Cu EPR in the normal state of Ortho-III YBa2Cu3O7-x

Min-Quan Kuang, Shao-Yi Wu, Hong-Kuan Yuan +4

The temperature dependences of g factors of underdoped YBa2Cu3O7-x (Tc approximates 86.5K) indicate that the pseudogap onset temperature T*( approximates 190 K) coincides with the…
