# Finite versus zero-temperature hysteretic behavior of spin glasses: Experiment and theory

@article{Katzgraber2007FiniteVZ, title={Finite versus zero-temperature hysteretic behavior of spin glasses: Experiment and theory}, author={Helmut G. Katzgraber and Didier H{\'e}risson and M. Oesth and P. Nordblad and Atsuko Ito and Hiroko Aruga Katori}, journal={Physical Review B}, year={2007}, volume={76}, pages={092408} }

We present experimental results attempting to fingerprint nonanalyticities in the magnetization curves of spin glasses found by Katzgraber et al. [Phys. Rev. Lett. 89, 257202 (2002)] via zero-temperature Monte Carlo simulations of the Edwards-Anderson Ising spin glass. Our results show that the singularities at zero temperature due to the reversal-field memory effect are washed out by the finite temperatures of the experiments. The data are analyzed via the first order reversal curve (FORC…

This hypothesis is strengthened by the crystal structure of 2 and by the absence of crystallographic phase transition for 1 over the whole temperature range of investigation as shown by XRPD, which could be at the origin of the unusually large hysteresis loop displayed by 1.
