At a superconductor/ferromagnet interface, the critical temperature of a superconductor is controllable by a magnetic exchange field of a ferromagnet. Conversely, magnetization of a ferromagnet is controllable by the superconducting condensation energy1,2). The interplay between superconductivity and magnetism is an important subject from the perspectives of both fundamental and applied physics.
In this talk, we will present our recent work on unconventional interplay between magnetism and high temperature superconductivity. We have found the coexistence of two different proximity interactions originating from the penetration of a magnetic exchange field into a superconductor and the leakage of superconducting condensates into a ferromagnet3). We have also demonstrated electric field control of these proximity interactions via strain-transfer from a ferroelectric material4). The results demonstrate that superconducting hybrids with ferromagnetic and ferroelectric materials are promising for the development of low-power and size-scalable cryogenic memory devices.
