Coercivity of Near Single Domain Size Nd2Fe14B-type Particles

Modification of the Interface Nanostructure and Magnetic Properties in Nd-Fe-B Thin Films

The effects of Nd2Fe14B grain size and Nd coating on the coercivity in sputter-deposited Nd-Fe-B/Nd thin films have been investigated in order to gain an insight into the coercivity mechanism of Nd-Fe-B magnets. Highly textured Nd2Fe14B particles were grown successfully on the MgO(100) single-crystal substrate with the Mo underlayer. As the Nd-Fe-B layer thickness t NFB was decreased from 70 to...

Size-dependent spin-reorientation transition in Nd2Fe14B nanoparticles

a r t i c l e i n f o a b s t r a c t It is well known that some ferromagnetic properties like Curie temperature are size dependent. In this Letter we will report that the spin-reorientation temperature of Nd 2 Fe 14 B material is also size dependent. By using a surfactant-assisted ball milling technique, Nd 2 Fe 14 B nanoparticles with different size about 6, 20 and 300 nm were successfully ob...

Investigation of the Effect Soil particles size on the Currency Time Domain Reflectometry for water content measurement

This study carried out on the provided textures at laboratory. The provided textures were infusedinside the PVC cylinder with 30cm height and 25cm diameter. The studied textures were loamysand, sandy loam, sandy clay-loam, clay loam and clay. After 24 hours of saturation, the soil watercontent of the samples was measured by oven-dry gravimetric and TDR methods. For each texturesat any stage of ...
