Hall effect spontaneous

Levin (1979) has studied the ternary compound CeCo2Si2. He reported the dependence of the spontaneous Hall effect and the magneto-resistance on the applied field. He observed anomalous galvanomagnetic effects due to an asymmetric distribution of charge carriers caused by their spin-orbit interaction with magnetic defects (Co clusters). 

The ordinary Hall effect originates form the Lorentz force experienced by the conduction electrons moving in the field H, while the spontaneous Hall effect arises... 

The use of neuroleptics in veterinary medicine to control wild and domestic animals provides another illustration of the deactivation effect and its independence from any presumed mental illness in the individual being treated (Booth, 1977 Hall, 1971 Rossoff, 1974). Hartlage (1965) found that Thorazine dampened the emotional responses of animals, thereby perhaps providing some clue to the widespread acceptance of the drug as effective in psychiatric settings (see also Mirsky, 1970 Slik-ker et al., 1976). Jarvik (1970) pointed out that the neuroleptics produce diminished spontaneous activity and emotional indifference in all animal species, including man, but he nonetheless argued for a specific antipsychotic effect.
