“…The fundamental magnetic properties of the Nd 2 Fe 14 B compound, spontaneous magnetization (M s ), Curie temperature (T c ), magnetic anisotropy type, spin reorientation temperature (T sr ), can be adjusted through element substitutions both in the rare-earth and iron sublattices [3,11,12]. For example, a Pr substitution for Nd makes it possible to avoid the application limitations of the above-mentioned permanent magnets at low temperatures since the Pr2Fe 14 B compound (as well as Y 2 Fe 14 B [13], Lu 2 Fe 14 B [14]) displays a uniaxial magnetic anisotropy in the whole range of the magnetically ordered state [15].…”

Magnetic hysteresis properties of nanostructured industrially manufactured Nd-Fe-B and Pr-Fe-B alloys on the base of a tetragonal Nd2Fe14B (2-14-1) hard magnetic phase (MQP-B, MQP-B+ and MQP-16-7 brands) have been investigated at 4.2 K in magnetic fields up to 58 T. The chemical composition of the alloys given in the certificates was defined more precisely. The grain sizes of the main 2-14-1 phase were determined. The average grain size is much smaller than a critical single domain diameter. Coercivity, remanence magnetization, saturation magnetization and maximal magnetic energy product were determined at 4.2 K and compared with those obtained at room temperature.

“…1d). As a result of heating the samples to activate the hydrogenation processes, the grains of the main phase (Nd2Fe14B-type) become larger, which leads to a decrease of the coercivity [19,20].…”

Magnetic force microscopy (MFM) and magnetometry, scanning electron microscopy (SEM) and atomic force microscopy (AFM) are used to study the magnetic and structural properties of the (Nd,Pr)-Fe–B and (Nd,Ho)-(Fe,Co)-B alloys. The alloys are synthesized using an arc or induction furnaces. The nanocrystalline state of the (Nd,Ho)-(Fe,Co)-B alloys is reached by two techniques, namely, melt spinning (MS) and severe plastic deformation (SPD). Hydrogenation and multistage treatment of (Nd,Ho)-(Fe,Co)-B alloys, which includes severe plastic deformation of melt-quenched ribbons and subsequent heat treatment, is also used. The surface morphology and domain structure of samples are studied. These pictures are used to interpret the observed magnetic hysteresis loops of the samples. It was found that multistage treatment allows one to obtain samples with higher values of coercivity due to the formation of a special microstructure with oval grain (the aspect ratio equal to ∼ 3).
