Measurements of the penetration coefficient of a radio-frequency electromagnetic field as a function of the strength of a stationary magnetic field have been performed. Two variants of using cores made from lanthanum manganites are analyzed. It is shown that cores made from lead-doped lanthanum manganites allow measurements of magnetic fields to be performed in the range 80–4×106A/m. A sensitivity of up to 2.5×10–2%/A/m can be achieved for fields of 80–8×103A/m Полный текст |
