摘要： The invention relates to a magnetic strip, wherein the strip has a magnetic easy axis which is axially parallel to a transverse axis of the strip. The strip is cut to length, from strip material made of a semi-hard magnetic crystalline alloy, along a transverse axis of the strip material substantially corresponding to a length (l) of the strip. The strip material has a magnetic easy axis which runs axially parallel to the transverse axis of the strip material.

摘要： A seamless, rotationally symmetrical hollow blank formed by a non-cutting operation from a deformable permanently magnetic alloy is provided, said alloy consisting essentially of 5.0 to 20.0 percent by weight cobalt, 20.0 to 35.0 percent by weight chromium, for the remainder iron and impurities caused by melting and/or by chance. The seamless hollow body is suitable in particular for use in hysteresis clutches, hysteresis brakes, and position measuring devices. Furthermore, non-cutting shaping processes for producing the seamless rotationally symmetrical hollow body are provided, with roller spinning being preferred.

摘要： A marker for employment in a magnetic anti-theft security system is composed of an oblong alarm strip of an amorphous ferromagnetic alloy and at least one activation strip applied onto the alarm strip and composed of a semi-hard magnetic alloy. One or more spatially separated regions that are composed of a non-magnetic phase are introduced into the activation strip with a thermal treatment. The semi-hard magnetic alloy has a coercive force H.sub.c of 15 through 100 A/cm and a remanence B.sub.r of at least 0.8 T.
