Some experimental aspects of spin glasses: A review

摘要: Abstract We present a working definition and general description of spin glass discuss number different systems, including metals, semiconductors insulators. In this review we the current status experimental spin-glass research its relationship to dynamics. salient features recent results, mainly published in past five years, on susceptibility, magnetization, heat capacity, high pressure effects, phonon-thermal conductivity, neutron scattering, nuclear, electron muon resonance, Mossbauer, optical, torque transport measurements various systems. report successful applications fractional exponential relaxation function frequency dependence susceptibility time thermoremanent magnetization. also new results observation second-transverse longitudinal modes predicted by triad theory dynamic critical scaling linewidth along with theoretical interpretation. addition, correlation times for systems measured studies, temperature which is agreement Huber. Concerning possible existence phase transition at cusp temperature, summarize evidence.
