Cold neutrons can be spin-polarised and reflected from interfaces. This technique can be used to reveal the magnetic profile of ultra-thin films (<3 nm thick) and 2D materials, revealing insights into magnetic proximity effects and superconducting penetration depths. Here I will review some recent applications of the polarized PLATYPUS reflectometer at ANSTO, and present the current international trends [1-3]. I will present a new Python library that allows for the solution of the 1D Schrodinger equation, necessary to model polarized neutron reflectometry data.
