Temperature Dependence and Critical Behaviour of the Resistivity Anisotropy in Ferromagnetic Metals

Abstract

The resistivity anisotropy in ferromagnetic metals due t o spin-orbit interaction is considered with spin correlation taken into account. The obtained temperature dependence of AQ shows a round peak in accord with experiment. In the critical region d(Ae)/dt diverges as ( -t)l-(a+q) ( t = = ( T -Tc)/Tc, magnetic field h = 0), where pl is the cross-over exponent.L'anisotropie de la resistivite, causke par l'interaction spin-orbitale, dans les metaux ferromagnetiques est calculee en consid8rant aussi la correlation des spins atomiques. La dependence de An avec la temperature montre un pic arrond8, en accord avec les resultats Bxperimentaux.

Employees' right to keep and bear arms … at work?

“…36 Moreover, any employer that fires, disciplines, demotes, or otherwise punishes an employee because the employee is in possession of a licensed firearm in his or her vehicle may be liable for civil damages and subject to an injunction. 37 Under the statute, employers are permitted to prohibit an employee's possession of firearms on their property if that employee is otherwise prohibited by state or federal law from possessing a firearm.…”

The Uses and Abuses of Convictions Set Aside under the Federal Youth Corrections Act

“…49 They may be statutory. Some states take from convicted felons such privileges as voting, 150 holding public office, 151 testifying in court, 152 serving as jurors, 53 or acting as a legal entity. 1 54 Other disabilities attach when someone in the private sector learns of a conviction and consequently refuses the offender a benefit such as employment.'…”
