Using a Keldysh formalism, we study supercurrent (SC) transport in severaltypes of diffusive ferromagnet(F)/superconductor(S) configurations. We separateout the even- and odd-frequency components and identify the relativecontributions from the singlet and triplet channels. We first consider 1DJosephson structures consisting of a uniform SFFS structure and a trilayerSFFFS configuration. Our results demonstrate that for SCs flowing perpendicularto the FF interfaces, incorporating a conical texture yields the most effectiveway to observe the signatures of the long-ranged SC. We also consider threedifferent types of finite-sized 2D structures subjected to an applied magneticfield: a uniform SFS junction, and two SFFS configurations with differing FFbilayer arrangements. In one case, the FF interface is parallel with the SFinterfaces while in the other case, the FF junction is oriented perpendicularto the SF interfaces. For the uniform SFS junction, we analytically derive themagnetic field induced SC and pair potential, providing insight into thevariations of the critical SCs and proximity vortices. Our extensivecomputations demonstrate that the induced long-range SCs can penetrate deeplyinto uniform FF bilayers when singlet SCs flow parallel to the FF interfaceswhich is in stark contrast to configurations where SC flows perpendicular tothe FF interfaces. We pinpoint the origin of the induced triplet and singletcorrelations through spatial profiles of the decomposed total SCs. We find thatthe penetration of the long-range SCs associated with SCs flowing parallel tothe FF interfaces, are more pronounced when the thickness of the F strips areunequal. Lastly, we show that the corresponding experimentally accessible SFFNspin valve presents an effective platform in which the predicted long-rangeeffects can be effectively generated and probed.
