The analysis of ZrCo:Co films with varying Co layer thicknesses reveals distinctive magnetic properties and behaviors. Despite significant roughness, the films exhibit uniform surfaces and complete crystallization at the nanoscale. Magnetic studies show positive remanence anisotropy, decreased coercivity Hc and remanent magnetization Mr with increasing film thickness, along with a linear correlation between thickness and surface roughness. Exchange interactions between grains and layers influence magnetic properties. Ferromagnetic resonance analysis demonstrates a direct correlation between film thickness and magnetization orientation preference, notably at δCo = 200 nm. These findings underscore the critical role of film thickness in determining microstructural and magnetic properties, offering insights for magnetic device and nanotechnology applications. Understanding these relationships may lead to thickness‐tunable magnetic materials. This study uniquely explores ZrCo:Co films, delving into how their magnetic properties vary with Co layer thickness, revealing novel magnetic behaviors.

This work focuses on the study of the microstructure and magnetic properties of nanocrystalline powders of Sm4ZrFe33, prepared by high‐energy ball milling. The Sm4ZrFe33 compound adopts a monoclinic structure (space group Cm). Upon annealing, these Sm4ZrFe33 samples exhibit notable variations in their extrinsic magnetic properties, closely linked to temperature fluctuations. The investigation delves into the correlation between morphology, grain size and magnetic characteristics. A significant enhancement in coercivity (Hc), remanent magnetization (Mr), and maximum energy product ((BH)max) is observed, primarily attributed to the finer grain structure present in the samples. Particularly noteworthy, among all annealed specimens, the nanocrystalline Sm4ZrFe33 compound annealed at a temperature of Ta = 973 K demonstrates the most promising magnetic properties. This specimen exhibits a coercivity Hc of 18 500 Oe, remanent magnetization (Mr) of 58 emu g−1, maximum energy product ((BH)max) of 5.18 MGOe, Curie temperature (TC) of ≈804 K, and magnetic anisotropy field (Ha) of 115 980 Oe. These research findings pave the way for future investigations and applications in the realm of permanent magnets, spintronic devices, and magnetic recording, utilizing nanocrystalline alloys based on the Sm4ZrFe33 compound.
