Abstract
The interplay of superconductivity and magnetism is a long-standing topic that attracts not only the academic but also the industrial interest. In particular, the high temperature superconductor with the superconducting transition Tc above the temperature of liquid nitrogen retains as a strong candidate for various practical applications, such as temperature sensor, current filter and quantum computation. In this study, the layer of YBCO is fabricated in contact with various manganites (so called F-, C- and A-type) and formed as herostructures. Their structural, electrical and magnetic properties are investigated. The thickness of manganite is used to fine tune the strength of effective exchange field. Interestingly, the proximity effect of manganite on superconductivity is observed with different fashions in different type of herostructures. Some surprising phenomenon are observed and ascribed to the modulation of superconducting gap.
