Popis: | The temperature dependences of magnetization higher harmonics were studied experimentally in single-domain YBa2Cu3O7−x samples above Tc. YBa2Cu3O7−x magnetization nonlinearity was found in different samples up to temperatures T = 103–112 K, which is much higher than the temperature of transition into the superconducting state of the given compound. The observed specific feature of YBa2Cu3O7−x magnetization is associated with the occurrence of pseudogap state in this compound. |
