| Research Abstract |
A very sensitive thin film sensor was developed using a coplanar line fabricated from SrTiO film, amorphous CoNbZr film and Cu/Cr film. This film enhanced the sensitivity of the magnetic field sensor, a phase change of more than 100 degrees/Oe and gain of over -40 dB being achieved simultaneously. The sensor with SrTiO film enhanced the sensitivity about 1.6 times greater than that with SiO2 film because of the high permittivity of the SrTiO film. A small phase change was detected using a Dual Mixer Time Difference (DMTD) method when a weak magnetic field was applied. The sensor was applied to magnetocardiogram (MCG) measurement without magnetic shielding. Measurement of the MCG signals at 16 points without magnetic shielding were successful, and these signals were found to roughly agree with MCG signals obtained with a SQUID.
