Abstract
The present paper presents results concerning on structure, magnetic properties and magnetization reversal processes in the as-cast Pr8Dy1Fe60Co7Mn6B14Zr1Ti3 alloy in the form of 1 mm plate. The XRD studies revealed coexistence of three phases dominant Pr2(Fe,Co)14B and minor á-Fe and Fe3B. The remanence-to-saturation ratio Jr/Js equaled 0.66 and indicated on existence of strong exchange interactions between hard and soft magnetic phases. The analysis of Mrev vs. Mirr dependences, the pinning mechanism was detected in studied alloy. Keywords: bulk alloys, magnetic properties, magnetization reversal processes
Highlights
Further studies concerned on magnetization reversal processes in bulk alloys with the same composition [19]

Due to the fact that internal structure and properties of material prepared by various techniques could be different, we decided to study phase composition, magnetic properties and magnetization reversal processes in 1mm plate of the fPorl8lDowy1iFneg60pCaop7eMr.n6B14Zr1Ti3 and it was the main aim of Experimental part The ingot sample, corresponding to chemical caorcmmpoesltiitniognoPf rh8Digyh1Fpeu60rCitoy 7oMfnc6oBn14sZtrit1uTei3n, twealesmobentatisnuenddbeyr low pressure of Ar
Summary
Further studies concerned on magnetization reversal processes in bulk alloys with the same composition [19]. In investigated alloys in form of tubes, the mechanism of magnetization reversal based on nucleation and pinning processes. The room temperature major, minor hysteresis loops and sets of recoil curves were measured using LakeShore VSM 7307 in external magnetic field up to ~2T. Magnetization reversal processes were studied using reversal recoil curves.
