Spin glass behavior probed by various methods with different time- and space-scale of observation: Ising spin glass Fe 0.50 Mn 0.50 TiO 3

Abstract

Under the expectation that the behavior of a spin glass (SG) system shows various aspects depending on the time- and space-scale of observations, we have studied the typical Ising spin glass Fe0.50Mn0.50TiO3 by measuring dc-magnetization, ac-susceptibility, Mossbauer spectrum, neutron scattering intensity and μ+SR time spectrum. We have demonstrated that the application of various methods with different time- and space-scale of observations to the same system is useful to clarify the property of the spin glass freezing, the Ising character and the de Almeida and Thouless-line.
