“…These data suggest magnetic interactions between adjacent crystallites within these films. [ 33,34 ] However, with decreased thickness to 10 nm, a notable decrease in H c and (BH) max is observed, dropping to 16.6 kOe and 1.03 MGOe, respectively. This evolution highlights the significant impact of thickness on the magnetic properties of these films.…”

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.

Rare-earth-transition-metal intermetallics show very interesting magnetic properties for numerous applications (hard magnetic materials, magnetic refrigeration . . . ). This paper is devoted to the study of the structural, magnetic and magnetocaloric effect (MCE) of the intermetallic nanomaterials PrCo3, which derives from the PuNi3 type structure. This system crystallizes into the rhombohedral structure (R 3m space group). PrCo3 compound exhibits a second order ferro -paramagnetic transition at around 330 K. This 1:3 system, based on a stacked Pr2Co4 and PrCo5 units, has a magnetocaloric effect of 1.3 J/kg K at low field. In addition, we demonstrated that the MCE derived from phenomenological and experimental approaches were in agreement.
