Abstract

Transport behavior that is characterized by a low-temperature electrical resistivity that displays a power law behavior ( ρ ( T 0 ) T s ) with an exponent of s < 2 is commonly observed in magnetic materials in both the magnetic and non-magnetic phases. We give a pedagogical overview of this phenomenon that summarizes both the experimental situation and the state of its theoretical understanding. We also put it in context by drawing parallels with unusual power law transport behavior in other systems. View Full-Text
