Multiferroic (ferroelastic/ferromagnetic/ferrimagnetic) aspects of phase transitions in RCo2 Laves phases.

Journal of physics. Condensed matter : an Institute of Physics journal

Driver SL, Herrero-Albillos J, Bonilla CM, Bartolomé F, García LM, Howard CJ, Carpenter MA.
PMID: 24441049

Magnetic phase transitions in RCo2 Laves phases with R as a rare earth element are accompanied by changes in crystallographic space group. For purely structural transitions they would be described as improper ferroelastic and therefore fulfil the condition for...

AIMS: There is a need for more biologic research in autistic disorder (AD) to determine if biomarkers exist that would be useful for correlating to symptom severity and/or clinical improvement during treatment. Given the fact that AD is 4...

Distributed Learning, Recognition, and Prediction by ART and ARTMAP Neural Networks.

Neural networks : the official journal of the International Neural Network Society
