Abstract
The magnetic response of the strongly underdoped Y0.47Pr0.53Ba2Cu3O7−δ was investigated. We found the presence of superconducting and magnetic orders deep into the paramagnetic state, up to 200K, which manifest as diamagneticlike response and hysteresis, respectively. We propose that the main source of irreversibility in this T range is the softening and melting of the glassy state into a viscous liquid of entities that behave like superparamagnetic particles with antiferromagnetic cores.
