Manganite sensor for measurements of magnetic field disturbances of pulsed actuators

Abstract

Magnetic field sensors based on polycrystalline Lao^Si-o.ipMnt^ films were used to measure the magnetic field distribution and disturbances during the operation of an electromagnetic launcher. Hollow cylinders made from dural aluminum and iron were used as propelled objects inside the solenoidal coil. The obtained results revealed the ability of manganite sensors to rapidly measure changing high magnetic fields of arbitrary waveforms.
