High-temperature superconductors (HTSCs) exhibit unconventional normal state electrical resistivity, diverging from standard Fermi-liquid behaviour. Resonance scattering is a major contributing factor to this anomalous resistivity, where charge carriers strongly interact with collective excitations like spin fluctuations or impurity-induced localized states. This mechanism is particularly relevant for cuprates, where strong electron correlations and a complex energy landscape result in non-trivial temperature dependence of resistivity. This behaviour often manifests as a linear behaviour over a wide range. We discuss the microscopic origins of resonance scattering, its impact on the transport properties of HTSCs, and its role in understanding the crossover between the normal and superconducting states. We also examine experimental signatures and theoretical models that describe this phenomenon, highlighting.
