Paper presents the results of investigation carried out on the magnetostrictive and magnetoelastic characteristics of high-permeability Mn0.51Zn0.44Fe2.05O4 ferrite. During the investigatation of magnetostrictive characteristics of the ferrite, the semiconductor strain gauges mounted on the frame-shaped samples were utilized. The same frame-shaped samples were used for investigation of magnetoelastic characteristics of Mn0.51Zn0.44Fe2.05O4 ferrite. Presented results confirmed that high-permeability Mn0.51Zn0.44Fe2.05O4 ferrite has near-zero, negative magnetostriction. Moreover, in spite of its low magnetostriction, this ferrite is highly sensitive on steresses from external forces.PACS : 7550G, 7580

Les différences des états magnétiquement neutres (DNS) d'un ferrite de Ni-Zn soumis à des désaimantations thermiques et magnétiques parallèles et perpendiculaires apparaissent dépendre distinctement de la taille moyenne des grains, ce qui est discuté.

Silicon vertex detector for superheavy elements (SHE) identification has been proposed. It will be constructed using very thin silicon detectors about 5 μm thickness. Results of test of 7.3 μm four inch silicon strip detector (SSD) with fission fragments and α particles emitted by 252 Cf source are presented
