Abstract

We investigated the influence of the magnetic permeabilities of the magneto-optical (MO) tertiary TbFeCo targets. Films were sputter-deposited by using a magnetron rf-dc sputtering system. Target B with a low magnetic permeability (5) was found favorable with regard to the target use efficiency (35%), and the uniform film thickness in the range of 1975 [Angstrom] to 2015 [Angstrom] over a substrate of 130 mm in diameter, compared to Target A with a high magnetic permeability (40). The difference of the Tb content between the sputtered thin rims and Target B was found narrower than that of the Tb content between the sputtered thin films and Target A. A low motor current was needed to rotate the magnet placed below Target B during the magnetron-sputtering.

Abstract

Granulation technique, introducing the self-healing ability to concrete, was developed by Koide, 2010 [1] based on the capsulation technology in the food/medicine industry. In this research, self-healing granules, containing cement compounds, chemical and mineral admixtures, were fabricated by a proposed granulation process and the capability of crack-self healing concretes incorporating granules was investigated. Self-healing granules, which were manufactured in advance by a roller mixer in the laboratory, were added to the concrete mixture as partial sand replacement, at a dosage of 70 kg/m3 concrete. In order to examine the self-healing performance of the concrete, a water passing test, in which a constant water head of eight centimeters flowing through a static crack of 0.2-0.4mm in width, was conducted for two months. Three different regimes of cured conditions i.e regime one (cured in water at 40oC for one month-short term range), regime two (cured in air at 20oC, relative humidity of 60% for twelve monthslong term range) and regime three (cured in water at 40oC for nine months and then in air at 20oC, relative humidity of 60% for three months-long term range) were applied to investigate the self-healing capacity of concrete. In this study, the capability of crack self-healing concrete was assessed by observating the reduction of water leakage over time, the closing process of surface crack and chemical analysis of deposit products in the crack. Based on the experimental results, the performance of self-healing concrete, improved by selecting the ingredients of granule and developing suitable method for granulation, will be discussed.

22. Magnetization measurements on RE2Fe17single crystals

Author

García-Landa, B., Algarabel, P.A., Ibarra, M.R., Kayzel, F.E., Ahn, T.H., and Franse, J.J.M.

Abstract

Magnetization measurements on single crystals of RE2Fe17(RE  Er, Ho and Y) have been performed in the temperature range 1.5–300 K and applied magnetic fields up to 12 T, along the hard (HMD) and easy (EMD) magnetization directions. In the Er2Fe17compound a FOMP has been observed for temperatures of 1.5–110 K.
