Abstract

The magnetoimpedance effect and the converse magnetoelectric effect in a planar heterostructure consisting of mechanically bonded layers of amorphous ferromagnet FeBSiC and piezoelectric lead zirconate titanate are studied. Magnetoimpedance was observed in the frequency range of 0.1-40 MHz and bias dc magnetic field of 0-300 Oe; the maximum magnitude of the effect at a frequency of 10 MHz reached 12%. The converse magnetoelectric effect was observed in magnetic fields of 0-50 Oe; the maximum value of the effect at the structure acoustic resonance frequency of 40 kHz was 1.45 G/(V/cm). Amplitude modulation of the magnetoimpedance by an electric field at the resonance frequency of the structure with a coefficient of ~1∙10─2 is found. Modulation occurs as a result of a combination of the piezoelectricity and magnetostriction of the layers, which leads to a change in the transverse magnetic permeability and the thickness of the skin-layer of the ferromagnet.

平面磁电异质结构非晶铁磁-压电体的磁阻抗:电场调制

研究了由非晶态铁磁体FeBSiC和压电锆钛酸铅机械键合层组成的平面异质结构中的磁阻抗效应和逆磁电效应。在0.1 ~ 40 MHz频率和0 ~ 300 Oe偏置直流磁场范围内观察到磁阻抗;在10兆赫的频率下，影响的最大幅度达到12%。在0 ~ 50 Oe的磁场中观察到逆磁电效应;结构声共振频率为40 kHz时，效应最大值为1.45 G/(V/cm)。发现在结构的共振频率处，电场对磁阻抗的调幅系数为~1∙10─2。调制是由于层的压电性和磁致伸缩的结合而发生的，这导致了铁磁体横向磁导率和蒙皮层厚度的变化。

期刊介绍： Journal “Radioelectronics. Nanosystems. Information Technologies” (abbr RENSIT) publishes original articles, reviews and brief reports, not previously published, on topical problems in radioelectronics (including biomedical) and fundamentals of information, nano- and biotechnologies and adjacent areas of physics and mathematics. The authors of the journal are academicians, corresponding members and foreign members of the Russian Academy of Natural Sciences (RANS) and their colleagues, as well as other russian and foreign authors on the proposal of the members of RANS, which can be obtained by the author before sending articles to the editor or after its arrival on the recommendation of a member of the editorial board or another member of the RANS, who gave the opinion on the article at the request of the editior. The editors will accept articles in both Russian and English languages. Articles are internally peer reviewed (double-blind peer review) by members of the Editorial Board. Some articles undergo external review, if necessary. Designed for researchers, graduate students, physics students of senior courses and teachers. It turns out 2 times a year (that includes 2 rooms)
