The nondestructive investigation of electronic and magnetic modifications at buried interfaces contributes significantly to the understanding of the underlying interactions. This knowledge is essential for the design of electronic devices based on complex quantum materials. Herein, the application of resonant X‐ray and neutron reflectometry for the study of perovskite transition metal oxide heterostructures is reviewed. Both methods are well suited for the nondestructive study of interfacial reconstructions and interactions of spin, charge, and orbitals at the nanoscale. Herein, cases are highlighted in which both methods are complementary and thus provide unique insights into the physics of oxide heterostructures. The design of perovskite transition metal oxide heterostructures with technologically interesting phases relies on the detailed understanding of interface reconstructions and their depth profiles. In this review, the focus lies on the complementary application of resonant X‐ray and neutron reflectometry as nondestructive techniques that provide important contributions to the understanding of the underlying interactions in these quantum materials.
