  Spin-polarized supercurrents can be generated with magnetic inhomogeneity at
a ferromagnet/spin-singlet-superconductor interface. In such systems, complex
magnetic inhomogeneity makes it difficult to functionalise the spin-polarized
supercurrents. However, spin-polarized supercurrents in
ferromagnet/spin-triplet-superconductor junctions can be controlled by angle
between magnetization and spin of Copper pairs ($d$-vector), that can
effectively be utilized in developing of a field of research known as
superconducting spintronics. Recently, we found induction of spin-triplet
correlation into a ferromagnet SrRuO$_3$ epitaxially deposited on a
spin-triplet superconductor Sr$_2$RuO$_4$, without any electronic spin-flip
scattering. Here, we present systematic magnetic field dependence of the
proximity effect in Au/SrRuO$_3$/ Sr$_2$RuO$_4$ junctions. It is found that
induced triplet correlations exhibit strong anisotropic field response. Such
behaviour attributes to the rotation of the $d$-vector of Sr$_2$RuO$_4$. This
anisotropic behaviour is in contrast with the vortex dynamic. Our results will
stimulate study of interaction between ferromagnetism and unconventional
superconductivity.
